I had a gapping session with our Pro last spring. Found my PW was at 44deg and my SW was at 52 deg the same as my Gap wedge. What an eye opener that was.
Since then I've bought 2 new wedges. 48deg and 56deg and discarded the SW. That was probably the best decision I've ever made, related to my bag ever. My game has tightened up brilliantly.
