High COR Impact ?

[axl]

Hello,

I'm considering making the switch to a high COR driver and was wondering if anyone can confirm the impact of a high COR driver. I read that it's about 2 yards per .01 COR, so going from the USGA approved .83 to .86 yields about 6 yards. Is that it? My swing speed (and distance) is on the low side - mid 90s (240 yd carry). Would the impact be even less?

I'm interested to hear comments of those who have made the switch (drives carried x before, now they carry y).

Also, does anyone now of a place in the SF bay area where i could hit a high COR driver?

Thanks in advance

There's no doubt about it. The feel/power at impact is clearly different and you'll easily tell the difference. So all things being equal, brand name, head size, reasonably correct shaft specs, you can expect at least 6 yards, I'd guess closer to 8-10.

So....the question might then be...will you play with it in a tourney round or for handicapping purposes. Some will call it cheating but I have thrown out there on this board many times that there are dozens of hi-cor drivers that are NOT on the USGA NC list. If you are just hitting it around for fun, it's moot.

Finally, I am not using one after using 3 previously as my R580XD TP is straighter, more forgiving with no loss in distance. I had to do a lot more homework though to get my shaft/head combo just right. Just get a hi-cor driver off the rack and just bomb it. It's a rush.

I agree, its always a rush hitting high C.O.R drivers, I'm not sure if its mental but it seems more fun. If the PGA tour was able to use high cor drivers they would have to make courses harder IMO. Its already bad enough as it is with the new balls coming out and in a year or so everyone would be 15yds longer on average.

I wonder if there would be a loss in Fairways hit %? hmmm...

If so, I want a 44" low C.O.R driver at .75 :beer2:

I have a couple of hi-COR drivers, and I have hit several more.

My SS is between 110-120 depending upon length of shaft. At 50"+, I will be around 120 mph, and I have found breakage to be a problem with both shaft and head...I even cracked a Cobra 454 head (not the Unlimited...but reg model.) In the last couple of years...probably 10 head or shafts have been damaged.

My longest drives have been with 50" shafts (with ultra light weight shafts ...60 grams or less) , and 500+ cc hi-COR heads...350+ yds. But the trade-off is...very low % FWs hit. And to be honest, I don't know why the USGA put limit on shaft length...the pros have been hitting 45" or LESS the last couple of years...practically no one plays anything longer. As for Hi-COR heads...maybe 10-20 yds, at least in my case...but breakage becomes a problem. Supposedly the higher the SS, the longer distance gains.

For maximum distance and accuracy...have an expert use a launch monitor and fit you with best combo of head (loft, size, etc.), and shaft. Erratic distance is no good...unless you are playing a 4-man scramble, or wide-open par 5.

I bought a TM 510 hi-cor to see what all the hype was about. Not impressed. I found no extra distance at all. I've also tried tour drivers from TM, Cleveland, etc. and I have found nothing to knock my 983K w/ Aldila R&D Proto 85-X out of the bag yet...

Good luck.

My stats are similar to yours, and I've only compared .86 to .83 with the 983K (Titleist Speeder 10.5) but found no big difference between the two.

That being said, I am currently using the R7 Max and it is probably the most consistent and longest I have driven for a couple of years so could do with comparing to the standard R7

[agoodgolfer]

Its hard to generalize the the added distance gained from .83 to .86. It will be different for everyone. It is completely dependant on ball speed, spin rate, etc.

If you want a rough estimate divide your average driving distance with a .83 driver by 83. Then multiple that number by 86.

That is a very rough estimate using the basic law of averages. The real numbers will verygreatly from user to user. A golfer with a lower spin rate and a higher launch angle will have the most advantage. Golfers with high spin rates will see very little distance gain. The higher rebound rate will just add more spin.

I personally have a gain of about 10 yards when I switch. I have played with Demolitionman many times and he gains at least 15 yards when he switches to a .86.

I had my first experience with HI-COR last October.

I played the last two holes with a R580 (.86) and XR-03 with comparable set-ups.

My drive on 17 with the R580 landed at 291 yards and it didn’t feel solid (mechanics not club).

However, on 18 with the XR-03 (normal conditions and playing a NXT Tour)....I drove the green. 329 yards. I've never done that. Checked my Nikon rangefinder three times.

I’m unclear on differences in design/face and technology but I was impressed. Now I’ve picked up a R580XD (.86) and sometime soon will compare all three.

I've seen the same numbers - 2 yards per .01 COR for 100+mph swings - but that supposed a perfect hit. What really counts for me are the misses. I'm better off with a bigger .83 sweet spot across the face (Cobra, MacTec, Tour Edge Exotics) than a small .86 sweet spot trailing off to an .81. I'd check out theCOR across the face before buying a non-conforming driver.
