Best club in my bad is the Ping 64 degree wedge, rated 60yds at full, 49 yards at punch, very easy to hit from 38yds up. Under that distance I dont generally need another full swing club, mainly because the flop shot of 37yds on SW works quite well, same with 29yd flop and 19yd flop.
I like my wedge gaps for punch and full

No more then 13yds, and I have the 105yd wedge as well but dont use it often. my factor for the ping 64 is the chip distance of 7yds. With full backspin it is great for short distance chips, and with "topspin" I can roll it out to 9yds on a flat lie. It comes in handy when you just miss the green to a pin only a few feet from the collar, or you need to check a downhill short chip.
