Hi,
As Faterson says - not so.
Suggest have a look at the forum posts on the subjects, you'll see lots of good info in there.
Search box - top right - key words. Its all there.
Let us know how you're going after 70 ranked rounds - its a bit early in your WGT career to making that call. Really - its just Practice, Practice and more Practice. Its just up to the individual how far they want to take it. Put in 700 ranked rounds and I'll guarentee you'll be right up there :-)
All the best.
Cheers Doug
