I currently play 710 AP2 irons with R300 Dynalite Gold XP shafts. I play to a 8.0 handicap index. Now, as a 64 year old, I'm losing iron carry distance. An 8 iron used to carry ~ 150 yards. Now a 7 iron is about a 148 yard carry. I've demo'ed a set of 714 AP1 irons and am planning to make the switch. However, I've noticed the AP1's with the standard XP95 shafts build to a D1 swingweight. My last 4 sets of Titleist irons have all been D2. Can the AP1 irons be built to a D2? If not, would going to the XP105 shafts bring the swingweight to D2? Aside from the difference in feel, would the characteristics of the irons be affected any other way? For instance, would any increase in club head speed with the AP1's at D1 be lost at D2? I believe the overall club weight should essentially not change, just the feel of the club head, right? If I go to the XP 105 shafts would I gain some stability (reduced shot dispersion) without any appreciable loss in club head speed?
