I am a senior golfer returning to golf after several years of hiatus because of injuries. I have previously used Microtaper and Rocket steel shafts in regular flex. I am currently using a Maltby KE-4 U30 club-heads with Graftec regular flex shafts. I hit my 7 iron to 150 yards. There is no test data available on this shaft to compare its frequency with other mid flex shafts. Golfworks range for regular flex shafts of 77-92 mph is too wide. When I hit the ball with these clubs the ball feels heavy on the club-face. Is this because this shaft falls towards the higher end of the regular flex range or is it because it is a mid flex point shaft as opposed to the the Microtaper and Rocket steel shafts which were low flex point? Would a mid-low or low flex point shaft be better? Although I am concerned that with KE-4 U30 the ball flight will be too high with a low flex point shaft.
The swing weight is D2. The specs of the clubs are not an issue. The clubs are balanced and swing weighted to with in 0.5 grams. Although I am not a professional, I am not novice at club making.
