Without an intimate knowledge of the actual ranking system WGT uses and there is some mystery surrounding going from Pro to Master, I will share that once my AVG went below 80, I started Teeing off further back. /wink
Now there are other "in progress" tourneys which I still replay as an Amateur and as of yet I still use the WGT Starter clubs, but as you may read elsewhere, the choice of purchased items can filter there usage once you become a Pro+.
Keep stroking - it will happen eventually and to note, once you get "paid", you do not fallback to a lower ranking, so enjoy the learning along the way.
