I've got 712 AP1 through PW (45) and Spin-Milled 48/54/58.  I prefer the Vokeys to the PW, so I'm planning on getting fit for 7I through wedges.  I may just reshaft the 7-9, and look at bending the 48 to 46 or 50, and adding a 50 or 46 SM5.  Most expensive scenario is AP2 714 7-PW, and a new SM5.  Comes down to gaps and feel.

You just need to recheck your gaps on the transition from AP1 to AP2 and maybe getting onoe or both adjusted a degree.
