Interesting thought gb13 and dpatt... I think u have the answer for where to start
I'm not adjusting loft 790, the gap perfect to me and are consistent thru the set.
I will be getting a 52 w/KBS WEDGE flex and then replace/or adjust 58 to 56/57 and take out 54, that will leave a slot for course special club (hybrid, 5wd, driving iron, 2nd putter,... Or lighter bag)
