RE: Axle to Axle length and Brace Height?
You're terrible! <img src=icon_smile_big.gif border=0 align=middle>
You know, that was almost the way I felt first time I drew a compound back in 77 or so. Never heard of the concept of 'letoff' before, and dang near ripped my shoulder to pieces when I hit that horrific 35% letoff. Didn't even touch one of those mechanized demonbows again for a couple of years.
But I do think the very short valley that a lot of single cams have, combined with the drastic jump from letoff to peak weight, is a killer on a bow's 'forgiveness' factor. That long dwell at peak is also a killer, especially at the end of a long day of 3D-ing. But, it's fast as blue blazes, you gotta admit that. And those little shorty bows are darned handy, light and maneuverable. Plenty accurate enough for putting an arrow in a critter's ribcage in a hunting situation.
I know I'm getting old and don't do much living on the raw edge anymore, but the gentle draw cycle and shooting characteristics of round wheel bows is SO much more pleasant to shoot. I would like to think a lot of people wouldn't mind giving up some of that speed if they just gave 'em a try.
