Noise is something I can't stand and the harness will have to be very quiet. BB I just watched a TV show showing deer hunting from a ground blind. The deer would look at it but not panic. The PT told me yesterday that she thinks I have a 70% chance of bowhunting this fall, well she is wrong on that one. If I have to shoot 45 lbs I'll be out there and maybe from a ground blind if I have too.
