I'm not blaming JW for anything. I'm trying to relate to him that a huge reason behind the decline of the N20 class was because of PROMINENT sailors going to the F18. Asking them why they flipped, it almost universally "theres more [international] competition in the F18's".

Also, I don't think the "too much power" argument sits well...

Lets make a list of former 20 sailors who went F18 shall we?
JC
Nigel/Alex
Krantz/Lennard
Titcomb
BK
... just to name a few...

I think you'd be hard pressed to say that those guys can't handle the power of the 20.
