As I stated before in this thread, a well prepped ASW-20 (with winglets) is pretty much there. A well prepped -20B works well in "heavy conditions."

Take it from a cross country pilot with quite a few hours in a A and C. Sucks on a ridge day @9lbs watching others cruise by you at speed, I won based on knowing when to climb for gap jumps (Mifflin).

I still say, for 90%,nut behind the stick is more important than the glider.
Deep pockets?
Go for it.
More time and training is cheaper and better.
