Capt Ray, 80% letoff is liable to cause your shoulders more problems than you think, especially with the cams on most of these new bows. You pull peak weight for a long ways and then you' ve got a sudden drop into the letoff. My shoulders are cratered and I found out real quick that those kinds of bows are flat PAINFUL to shoot, especially when you get a little too antsy to get the bow drawn and forget to baby the draw into the letoff. Then on the release, you feel the cam(s) roll back over and get to go through the pain all over again. It' s not good for your accuracy, enjoyment OR your shoulders.

I' d recommend something more along the lines of the Hoyt Accuwheel or Martin Fury cam in 65% letoff and using a relatively light draw weight. Both have a gradual buildup to peak weight and a much more gradual drop into the letoff. Something like that won' t be the fastest bow on the planet, by a long shot, but it' ll keep you shooting as pain free as possible and enjoying it more. A 50 pound compound will kill a deer every bit as dead as a 70 pounder, just not as far or fast.

Good luck.
