The wgt pro full set is my advice, if you intend to one day play the big clubs from the legend tees. The only low level set with high loft. Fast meeter is very challenging at first, but if you stick with it you will get used to it and so be best prepared for the high level clubs. I played this set through to the high 70's levels, where I started buying my current equipment.
Disclaimer: Don't buy this set if you are looking for the best scores possible right now. There are other low level clubs with which you will definitely shoot lower scores. They will however not be as good as a preparation for the high level clubs as the pro set.
If interested you can read more on my thoughts about club choice here.
One more thing: Play the free ball at least until you own the (high level) equipment of your choice. Paid balls eat your credits faster than you can earn them.

Edit: Too late, I see the credits were probably burning a hole in your hand. We all know that feeling. Anyway good luck with your new clubs.
Final tip: Don't upgrade your equipment with every level you advance. Better settle for a certain set and take the time to get used to it.
