Can I feel the difference in 10 grams between a Proforce V2 55, 65 or 75?
You will no doubt have a hard time feeling the difference of 10 grams in the shaft alone. However, choosing the correct weight in a shaft again depends on your control vs. distance factor. If a your main issue is more distance and your swing speed is less than 85 mph, then a shaft that weighs less than 60 grams would be a good place to start in the fitting process. Golfers between 85 and 100 mph should look at shafts in the 60 to 75 gram range to maximize both distance and control. To help the golfer at 100+ mph maximize control, their shaft should be around 70 to 85 grams.
