I just have to give thumbs up to Mini and Hans for their reasoned posts.

AHPC and NACRA have choosen a strategy for reasons I dont know. Now we just wait for Hobie to jump on the same bandwagon as the F16 market is becoming the next growth market.

Looks to me like the class have managed fine on their own.
