my position on wedges is that less is more.
i used to play with a 60, 56, 52, and pw back in high school, but have since gone to just a pw, 52, and 57. I use my 57 for virtually every wedge type situation around the greens (i always use the lowest lofted club i can though) and everywhere from 125 and in. I've found that works out better than trying to have a club for each yardage as it forces me and enables me to have a better "feel" for what i'm doing which makes all of my shots better.
the only time i use my 52 or pw when i could use the 57 is in the wind to keep it lower. I'd start a golf thread, but i'd be surprised if many posted. I think i may have done it once or twice before actually. It would be fun to have an explorer golf tournament but i'm sure that will never be more than a foursome or two in one location.
