Wedge question

Ok guys New Golf Irons, here's the scenario I've got a set of Callaway X-22s bought 2nd hand from one of the fine upstanding members of this forum. I have a pitching wedge and an approach wedge Golf Irons Store, but I'm having some difficulty around the greens. The wedges from this set hit REALLY well when I'm 50 meters out Golf For Sales, but those tiny little chips onto the green I have difficulty with over-hitting, or worse, edgeing the ball (which then worm-burnes over the green, leaving me in the same position on the other side). With a full hit I can get lots of loft. but not the case for the really short shots as the club design seems to favour distance over really short accuracy.So I'm thinking of buying a new wedge. Does anyone have any recommendations? I'm thinking a 60 degree Gap wedge that produces a lot of spin. I'd prefer either Callaway or Wilson as I can get them for FREE through my work reward program. I see that there are lots of wedges that are sold as individual clubs, how are these different from the ones that are part of a set?You see in this world there's two kinds of people, my friend. Those with loaded guns, and those who dig. You dig. The Man with no name
