If I custom order the PTM forged irons at -1/2″ shorter than standard, can Golfworks assemble the clubs to D2 swingweight? Secondly, does adding swingweight have any effect on the MPF or COG?
We should be able to get close to a D2. It depends partly on the shaft and grip you choose. 1/2″ shorter will generally lower the swing weight by 3 points and by adding 6 grams back we can make up for the shorter lengths effect. That is assuming at standard length the club would have been at D2. Adding up to 10 grams in the hosel moves the cg very little and not enough to effect the MPF or cg location of the club.
