I am upgrading my combo set from 710AP1/AP2 to 718 AP2/AP3 and was fitted with Nippon Modus tour 3 105 stiff shaft.
I was originally thinking of AP3 (4 - 6) and AP2 (7-P) to match what I have in 710AP1/AP2, but after looking at the loft specs, there is quite a gap and some have recommended on the Titleist discussion board to go with 2 Degrees strong for AP2 and 1 degree weak for AP3.
What I am concerned about, is that the bounce for these clubs were meant with the original loft, and changing them by 1 degree may not be that bad, but 2 degree especially on AP2 for the shorter iron may not be a great idea as I tend to have pronounced divots, especially with my short irons.
I was also quite impressed with hitting the AP3 vs AP2 - 7 iron and so I deceided to go AP3 (4-7) and AP2 (8-P), wherein I only need to change a 1 degree weak loft for the 7 iron, and 1 degree strong for the 8 iron. The gaps within the series is now about 4 degree apart.
I am about to order this and what to make sure my latter selection is reasonable, or should I switch back to the original selection opted by some on this board..
