even a flat shelfed bow can be tamed pretty easily with pressure points under the rest material if you so choose to go with shooting off the shelf. Not only does it minimize torque but it will also take away the need for a radius shelf.

The shelfs you will have problems with are sloped shelfs. Ones that arent prefectly flat or radiused but slanted so the arrow will fall off the side. You can help correct this by building up with leather and tapering it into a flat or radius shelf if you so desire. You can also do this with a flat shelf with a couple strips of leather (make it a slight radius without to much build up). I do believe the pressure point is a better gig but to each there own. Kinda feel the same way about shooting with a rest on a stickbow. Not that it dont work but we go this route to keep it simple. Nothing wrong in doing it, just one more thing to fail for you. Just something to think about during the long winters.....
