How much difference are you guys shooting indoors than on your hunting rigs? I'm caught in a bind so to speak. I shoot 68lbs hunting rig, but my target rig with spiral cams at 60# wears me out halfway through a 5 spot round. But if I go down in weight to much my float just goes away and I'm all over the place. I have considered trying a less aggressive cam that gives me a good holding weight but not burn me out drawing it. Does that sound to be an option?
