I hate saying it but I just donno, I keep on switching. All I can tell you is that I like rifle scopes because the better ones give me more light. Currently I have a B&L 1.5 X 6 X 36 Elite 4200 which gives me lots of light at magic hour (the last half an hour after sunset). I am thinking about using one of my Nikon 30mm scopes because it might give me more light. Sorry Roger but I have not found the perfect scope. I know one thing, there isn't one "crossbow" scope that cuts the mustard at magic hour! When I find it I will let you know for sure.
