Its all on there.

I carry 4 wedges

PW SW AW LW I couldnt do with out any really, they all come in useful. But I only carry a 3 wood at the other end so I am not pushed for space.

The AW is the x20 one and it made life so much easier than trying to hit a SW harder or PW softer, now I can just play a full shot with the AW for the 100yard mark.

Homer, will be intrested to know how you get on with your set up as one of your x wedges is only 1* higher than your SW (if you got one) You may have gone 3-pw I dont know.

Hope I aint peed u off, but if this is the case, think twice before using it as you might not need it.
