Ampa, yes there is one of my drop away rests on my neighbor's Pro 40. That's one of the reasons I'd like to try the Axis as I'm sure they will work with my rest. I understand not wanting to change what is working, I subscribe to the same theory most of the time myself especially when there's lots of money involved in 'trying" something new. The archery message boards are a dictionary of knowledge by regular guys like us that post their findings on new equipment. This takes away some of the fear of trying new stuff by sorting through opinions and thoughts first I'd like to see a robinhood with an Axis That would be a real feat!!!
