So if you soft stepped the NV Comp regular flex by 3 and it is still too stiff and heavy at 85 grams, and the Alta 66 gram A flex is too soft, I think you have some more experimenting to do. It sounds like you need to go closer to the weight of the Alta, or definitely less than the NV Comp at 85 grams. Maybe target 75 grams or less on the weight. As far as the flex, because every manufacturer is different and flexes do overlap, it is difficult to pin down where to start. Soft stepping the NV Comp by 3 should have been more flexible than most standard A flexes. Not sure if you’re feeling the weight more than the flex. And on the Senior flex on the Alta, since I don’t have the profile of it I can’t compare it to other A flexes to know if it is on the soft side of all A flexes, or average, or on the stiff side of all the A flexes in our data base. With all that being said, I will give you a couple to consider, but there is no guarantee these will work. Also, the Ping G410 irons take a .355 taper tip shaft, which somewhat limits our choices. The Aerotech Steelfiber 70 CW A flex is 70 grams but it’s flex profile is closer to the average R flex except in the tip where it is slightly stiffer than the Average R flex. The UST Recoil 65 gram R flex profile is right on the average for all R flex irons. The Kinetixx A flex is a true A flex in the butt section, with the tip section being more to the average of an R flex. The Kinetixx R flex is very similar in profile to the Steel Fiber 70 CW A flex. So you can see, the flex designations and the actual flex profiles from different manufacturers can be completely different. Again, I think you’re just going to have to do some experimenting, but do beleive you can narrow down the choices based on the weight. Not sure if this helps or just confuses, but hopefully gives you some direction.
