Tourspecgolfers Fitting Results

[+TourSpecGolfer]

Yesterday i participated in a test that had 3 new zelocitys, 2 older vectors, 1 new vector and the track man.

Here were my averages:

Swing Speed: 100 mph

Ball Speed: 147 mpg

Launch Angle: 13.7*

Back Spin: 3500-3800 ( too high )

Carry Average: 244 yds

Power Trasfer Ratio: 146

This average is based on my performance club the 10.5 Epon with DREV Tour R flex tipped to play soft. I was able to get my swing speed to 104mph but the increased speed didnt add any distance and usually increased spin. keep in mind i have some issues with my swing, i do often hit down on the ball which hurts my launch angle. I did however get a peak ball height of 28 yards in the air which is great as 30 is considered optimal.

Amatuers, a couple EPGA players, PGA wannabe's, and mini tour players participated. most of these guys didnt know much about equipment or fitting but 99% of all players used a shaft too stiff and a loft to low.

To my suprise the 105mph+ group did best with R flex shafts, these guys are good players with PTI ratings of 150 and above.

My advice to all of you is the same, softer shaft, higher loft no matter how much you think you know about equipment. A low spin shaft dont work if your PTI is below 150 score so dont even try it. Its usually technique that is giving you the unwanted spin. If your a high ball hitter, check your technique first, then adjust loft, and last shaft. Oddly the difference betweek a high kick shaft and low kick is only 1.6" in most cases. My second best results came from the cleveland launcher 460 10.5 with a tipped A flex shaft! how about that for a 101mph SS. The only import clubs tested were the EPON and Srixon ZR-600. The ZR-600 was perfect except for the launch angle. One of the EPGA guys was 16 yards ahead of all other clubs with my driver. 10.5 w/PT-6 Stiff, another mini tour player had the highest power transfer ratio of the day with it.

Was it the head or the shaft? Of course a combo of the two but it worked for the better player.

Of the machines tested the trackman was the most accurate as it tracks the downward flight after peak, but IMO not worth the extra money unless you own an OEM that does loads of driver testing. The zelocity was great and accurate with the most usefull readings but the new version we had didnt have half the programs written yet. The New accuvector pro is CRAP, not accurate, and hard to get going. The old accuvector was great as usual besides the fact its hard to do irons and fw's because its based on sound as well as photo.

We were trained on each of the various machines except the trackman and I came to the conclusion that if you have 25ft of space to swing and let the ball fly Zelocity is #1, If you are indoors and have 10-15ft of flight space the original accuvector takes the cake.

Great info Chris... it further confirms the need for more loft... especially for a recreational golfer like myself. And with my swing speed being below yours I definitely have to stick to R flex.... I guess you didn't try any of your Axiv shafts out? I'd be curious to see if they added yardage and their launch characteristics as I'm thinking of getting one from you. :tsg_smilie_cool:

When I return from fitting school I will start testing import clubs. Thing about that is I am testing it for my swing not yours.

Another thing we noticed from testing was that players that have a smoother tempo or not much wrist cock didnt see as much performance increase in aftermarket shafts because they didnt load properly. This was the case even for guys who had 108mph swing speeds.

Oh I know it's for your swing not mine :tsg_smilie_smile: but just as a poing of reference to compare the axiv vs stock shafts... I guess once you're done from fitting school you'll have lots of time to test all your clubs. :tsg_smilie_cool:

Agree 100% - the Axiv 6068m I bought from you is quoted for way less than my 110ss but it is perfect for me untipped :tsg_smilie_cool:

Yep - why I play X in my irons but S in my driver/woods (and wedges).

Chris or anybody in the know, could you explain to me the Power Transfer Ratio. What is it, how is it measured and what it contributes to defining the swing?

Chris or anybody in the know, could you explain to me the Power Transfer Ratio. What is it, how is it measured and what it contributes to defining the swing?

Power Transfer Ratio (PTR) also known as Power Transfer Index (PTI) is a percentage % calculated as Ball Velocity / Club Speed x 100%. This represents an indication of centeredness of impact between the ball and club face.

If you have a high club head speed and your PTI is low your hitting it off center. Have you ever noticed a slower swinger who can hit it past you? that means their swing is more efficent for its club head speed.
