RE: IMAC just too expensive
one point worth making is the referene to pattern...the pattern limit works because it applies to everyone, what is proposed here is exclusionary, it creates a class within a larger class - not the same thing and that's why the arbitrary limit doesn't work.
as for the other thing, maybe i haven't flown a 40% that was set up properly - the last one I flew was Jason's S's backup TOC airplane. Let's see I also flew QQ AW's 37% 300L - you know, his actual TOC airplane..does that count? I flew Peter Goldsmiths 40% Piper Cub. Does that count? Oh, I flew Bill Hempel's 36% Edge before anyone knew what an Edge was - the same airplane he took to the Masters, but I guess that doesn't count since it is so little.
I am not ignoring the benefit of a big airplane, I am simply not seduced by it.
