alosso:Looking at the OP, first priority are the wedges (+1 Courteney). Two short ones of those lvl40ish Pings will do for the moment.
The Ping wedges are very good. I used them until they introduced the Cleveland wedges. I still use the 54 degree 105 yard Ping as my 3rd wedge. As Alosso said get at least 2 shorter wedges and you might even consider dropping the hybrid and getting 3 evenly spaced wedges. If you do get the wedges learn all the shots with them. The punch with your wedges can be a life saver. It is like having twice as many wedges.
And the pink starter that you bought is just barely better than the starter that WGT gave you when you started. There are many good putters below level 48 that would help your game as much as anything.
