I would say that the US RC decision to include modern standard class gliders and 15 meter gliders ASW20B,C and Ventus 1 has produced a sustainable class, given those gliders an important place to fly other than sports class, helped us to create enough venues to provide challenging racing across a large country, and sticking to the IGC club class list would not have done so.

Congrats to Keith, and all the pilots who made this a success, given what looks like a good challenging contest.
