Over to the right ->->-> in the Search box type in ScottHope Equipment Tables. Best tool available when planning out purchases. (for the life of me can't figure out why its not pinned right at the top of the equipment page).
More directly to your question...
If you have an affinity for Ping, hang in there for the L81 driver and L83 irons. They can both carry you through into Legend. I know it seems like a long way off, but you continue to level up rather quickly until you reach the upper 80s/lower 90s.
Occasionally WGT will offer a "Bundle" deal on the L81/83 Pings or the L90 Taylormades that you can buy even before you reach those levels. These are both pretty good deals and if you happen to see one of them pop up I would go for one of those. When I reached somewhere around L84 I was offered the 90 Taylormades and still use them as a Legend. I'm not great by any means but can hold my own with these and a better ball.
Speaking of the ball, you can get some meter speed and distance help with these highly regarded balls (in order from cheapest to more expensive):
L13 Srixon/ L33 Callaway/ L35 Callaway/ L47-48 TM/ L51 Volvik/ L60-61 TM
Just remember to plan purchases and credit savings carefully. If you think the Tour Master tees are trying, just wait until you move to Legend, lol.
