I had a similar decision to make on those 2 ends of the bag. I chose 50,54,58 in the wedges. I basically go full pw, 3/4 pw, then 3/4 50,54,58. As soon as I try to hit wedge full I lose control.
The other decision was between 3 hybrid and driving iron. I'm still thinking about about getting a driving iron.
Regarding having bigger gaps in the higher lofts. I thought strongly about it but I kept the extra wedge so I had more options from 100 and in.
Good luck!
