Not all THAT much.

I think the old bows are fun! I tried for several years to get a 'classic compound' 3D shoot going at the club. Only compounds 1985 model and earlier, allowed. Rules were to be original IBO with targets 'about' 60 yards max and aluminum or fiberglass arrows only. I think it'd be a hoot, but nobody else wanted to do it so I gave up on the idea.
