I'd try to get the level 83 full set of G20's. They'll take you well into the Legend tier. By buying the set you save money and you can also sell back the hybrid to buy a 3rd wedge. You'll have to wait a few weeks though but it'll give you time to pick up more credits.
IMO this is the best advice you can get. The G20s are fantastic clubs with a slow meter speed, and you would never have to upgrade again if you didnt want to. They will knock off several shots every round!
The downside is you will need to earn more credits, but is well worth the wait.
Also totally agree with Ms Fish regarding 3 wedges.For the meantime really work on your short game, including putting as this is partly why your scores are not coming down. Use the forum search for tips and hints.
