I recently added a Gap wedge to my bag...don't know how I played without it...
105-115yds 48 degree PW (nike CCI iron set)
95-105yds 52 Nike VRPro Hex GW 10 bounce
56 Nike VRPro DS SW...love the dual sole but find it difficult to hit full
I almost exclusively use the gap wedge for chipping and pitching out to 115yds and use the SW as a specialty shot wedge (sand/lob)
