I will second, third, fourth, etc holding out for the g20s. I struggled through early on as a Master in the same position you are - low level with no really good options at the time. I'm actually really disappointed in myself for not having made TM by this point since buying the g20s at L59.
I'm expecting to be able to hang on to the g20s through Legend with a possible driver upgrade and more complementary wedges once I get there.
If you weren't already in Glamouflage, I'd send you an invite for the YGCC - all about the ability to fire low even with inferior clubs. (And heck, you're knocking on the door of TM already as it is!)
