Excuse me while I ramble on a bit.
You have fairly good stats and are playing lots of rounds. That means you'll be progressing fairly quickly if you keep up the current pace.
So, my personal suggestion would be... get a couple of cheaper wedges, the ping gorge maybe, and use those until you get to where you are ready to spend some serious credits for the upper level wedges.
If you do that and learn how far they pitch and punch from various lies it's really all you need for now, and it won't clean out your credits.
Good luck,
Dave
my suggestions:
PING Gorge 60° Wedge (L42+)
PING Gorge 56° Wedge (L41+)
