When I used to play a 45 Degree Wedge, I went 50,54, 58. With the 44 Degree Wedge in the T150 I actually went to a the set 48 Degree wedge. It works well for me as I like it more on full shots. I left the 54 and 58 wedges alone because I never hit full shots with them and I like the yardages on half, pitch and chip shots. Bottom line is I'd play the wedges at the bottom of your bag that you are comfortable with and not worry about a degree or two difference in gapping.
