jaybit Posted October 12, 2004 Report Share Posted October 12, 2004 Just wondering if most people outside of the USGA boundries use drivers like these. Is there a huge benefit from .83 to a .87 COR. Id love to get one if im gonna gain 15 yards. This driver would definitely be for days where i just hit it up with buddies. When im in a tourney its usually my 975D bc for some reason its a good pressure club for me. BTW where is the sweetspot on the r7 max.

When im in a tourney its usually my 975D bc for some reason its a good pressure club for me. BTW where is the sweetspot on the r7 max. I always play high COR drivers, I don't play any tourneys that matter so I honestly don't feel like a cheater. That being said the Srixon 404 is my best friend. I'm playing a closed face version waiting for my square face spec to arrive, TS girl plays the R7 Max and it too is fantastic. The hottest feeling faces are the OnOff, the Inpres and a few others, they reach COR of 0.87 and totally leap off the face, it seems to put more spin on the ball IMO and I usually need shafts that keep dispersion tight. 983k H.C.R believe it or not is my best selling high C.O.R driver.

xxio Posted October 12, 2004 Report Share Posted October 12, 2004 The R7 max with the 55gram shaft is a solid club. When the R7 first came out i demoed it 9 holes alternating against my R300Tour/Six combo. Hardly any difference between the two when the R7 max was set to nuetral maybe little better dispersion but I attribute that to the R7 being a S flex when I might be more of an X in that shaft. IMHO the TM Japan heads with the lighter shafts have better feel because they are probably heavier heads. Hotter heads give me better ball speed readings but all in all the distance gain is maybe 5-10 yards solid on solid. If your going the non-conforming route just for fun anyway check out the Japanese component heads some have .90 Cor claims. Quote Link to comment Share on other sites More sharing options...
jaybit Posted October 12, 2004 Author Report Share Posted October 12, 2004 the new mizuno composite looks really nice but i always wanted to change my trajectory without putting lead tape or changing all the parts lofts and angles. I know the r7 wont cure a banana slice but still.... does the r7 max still come with that goofy headcover and is the weight kit tp or retail.

alohano Posted October 12, 2004 Report Share Posted October 12, 2004 Yes, there is a huge benefit! You'll realize it the second you hit a non-conforming driver solid. I have a non-conforming head with a Fuji Six and I'll never use a conforming driver again. I have a clear conscience cuz I check the USGA list every Monday and my driver is not on it, probably will never be on it. There are dozens of drivers that are hi-cor that are not on the list. So if you play in tourneys and otherwise give a rip, you might want to consider getting one that isn't on the list. Then you only have to deal with the technicality of the head not being on the list. If you are playing for fun with it, the point's moot but you sure as hell will notice the difference. Quote Link to comment Share on other sites More sharing options...

R7 max is just like the retail R7 US version with a non conforming face. However like I said I feel the Japanese versions are better feeling because they seem to use heavier heads. Weight Kit is still 10-2-2-10 only and same goofy headcover. Quote Link to comment Share on other sites More sharing options...
jaybit Posted October 12, 2004 Author Report Share Posted October 12, 2004 i know the weights in the head are the same but the weight kit itself, is it the retail or tp weights that are in there case with the wrench, or do i get a weight kit at all.

buns Posted October 14, 2004 Report Share Posted October 14, 2004 I bought a titleist 983k H.Cr and have subsequently bought a non H.Cr version with the same specs..... the H.Cr puts a rake more spin on the ball and I couldnt stop the ball ballooning as compared to the same (but non H.Cr) which doesnt..... so in the end of the day, the non H.Cr goes further for me...... ad Quote Link to comment Share on other sites More sharing options...

I notice all high C.O.R drivers have more spin and shaft really makes a bigger difference the hotter the face. I noticed I need Stiffer high kick shafts with really hot faces. Fuji 784HK is great and so is the PM702. Quote Link to comment Share on other sites More sharing options...

How is the sound on this is it as pingy as the us retail? Sorry just saw this thread again now. I have not hit the US retail. But in my opinion most of the Japanese heads that have lighter shafts have heavier heads and somehow feel and sound better than their US counterparts. I used to play a Japan TP that originally had a 569 at D2 compared against my friend who has a US TP 757 at D2 we both think my TP feels better.

palle Posted October 21, 2004 Report Share Posted October 21, 2004 Well i´m living in Sweden and plays the R7 max and I can say that 0.86 cor really makes no different. The swedish golf federation made a test betwen 0.83 and 0.86 driver in a robot machine called "iron byron". If hit in the sweet spot high cor drivers were maybe 10 yards longer BUT if it didn´t´hit sweet spot the high cor was sometimes 10 yards shorter! The sum was that maybe most amateurs really don´t use the benefits of high cor drivers. The right shaft and loft makes more different.

The sum was that maybe most amateurs really don´t use the benefits of high cor drivers.The right shaft and loft makes more different. Your post is contradictory. You say it makes no difference yet you say "if hit in the sweetspot high cor drivers were maybe 10 yards longer BUT if it didn't hit sweet spot the high cor was sometimes 10 yards shorter". "The right shaft and loft makes more of a difference". Noone disputes this. The question is ...... on the same head/shaft but different COR values is there a difference......You answered it on your first part for the combo and the swing speed that was tested by your Federation is was 10 yards. I bet at a higher SS or a better combination of shaft -head-loft it could be bigger. I play a high Cor driver because it is "legal" here as well. My R300 Tour just leaves the face faster than my TP. They both have Fujikura Six S flex tipped 1 1/4". The model you tested seemed to lose 10 yards on mis**ts. That could be a design issue. I find the newer drivers especially the new Cobras and the TM XDs to be more forgiving all across the face compared to drivers of 2 years ago. A lot of amatuers may not benefit from Hi Cor. There have been several discussions on whether Hi Cor benefits slow SS or higher SS more. But there still is a difference. For me it is around 10 yards carry but it seems to add a little roll as well. Quote Link to comment Share on other sites More sharing options...
palle Posted October 21, 2004 Report Share Posted October 21, 2004 Well of course if you try 30 different combos, you will hit h.cor drivers farther. I talked with a clubmaker who designes drivers for a brand here in sweden about this and he says that it will make max 10 yards with everything properly fitted, as you wrote. But who plays with right fitted drivers out there? I totally agree with you that if you compare two custom made identical drivers, one high cor, hopefully the h.cor will go farther. But my point is that some of thoose plain retail drivers won´t difference so much. Or maybe you have tested this to plain retail drivers? Finally I can´t understand why you make your opinion based of trying two different drivers. A TP and R300 are not same built. Try one R300 tour and one 300 tour, that would be interesting.

buns Posted October 21, 2004 Report Share Posted October 21, 2004 There is no arguing on this point really..... just have a look at the definition of COR and it answers itself! On a perfect hit, a high COR driver should go further and that is all there is to it! That said, as mentioned, a strike which is not perfect will not adhere to these rules ad Quote Link to comment Share on other sites More sharing options...

You are trying to start an argument from another point...proper fitting. AGAIN noone will dispute that a properly fit club will have more effect on distance than Cor. I believe the first poster asked if Cor makes a difference? He did not ask if a high kick shaft with high loft or a low kick shaft with a low loft head makes a difference. I guess I made an assumption that he was already fit properly and that he was only worried about Cor values? Please correct me if I am wrong So does it make a difference? You answered that in your post it does 10yards....but then you say it doesn't make a difference. Just pointing out the contradiction in your post. I cannot compare 300 Tour to R300Tour because I don't have a 300 Tour. I made a comparison to what I had personal experience with. I was also comparing the speed of which the ball left the face for me. I did not compare loft, trajectory, forgiveness, etc. I was just comparing my "perceived hotness" of how much faster the ball left the face. I was comparing solid on solid with as similar set ups as I have in my bags. AND COR MADE A DIFFERENCE. Quote Link to comment Share on other sites More sharing options...
alohano Posted October 22, 2004 Report Share Posted October 22, 2004 Gee, folks.....to answer the poster's original question...YES! If it didn't, there wouldn't have been all the testing, controversy and the USGA list of non-conforming drivers. Personally, yes and then some! Significant difference and I love it!
