Ok Lowpost, I've decided on my plan of action.

I'm gonna get the clubs assembled by bighit, and when it comes to getting new irons I'll have a pro club-builder do it for me, and at the same time get him to adjust the wedges appropriately.

Is it fair to assume that any club-builder worth his salt would be capable for spining/FLOing, frequency matching, swingweight matching and MOI matching? Generally would they be prepared to use clubheads that I supplied?

I just did some static measuring, and I'm about 6'5" with a WTF of 39.5". So according to the charts that puts me at 1.5" longer, and 3* upright, is that about right? As I understand it, for each inch you add in length you get 2* more upright, so 1.5" represents 3* which is roughly what I'm after. Though I do understand that this would be a starting point, and ideally you would do a dynamic lie test.

Anyway, thanks for all your help!!

Chris
