I'm checking on that stuff now. Also wondering about using smaller blocks (40mm carbo's, or even 20's?), and going to a cascading type system to get higher purchase.

Any info on how they got a 12:1 system out of the rigging on the M20. Looks like part of it travels up the boom (I don't have one), maybe it's a 6:1 with a 2:1 cascade on it?
I dunno, maybe I'm just looking for ways to spend $$
