The Whittler - "Put your square on and when it touches the feather rest then put your nock set where you usually do. Start shooting and you can adjust from there."
Yeah, that is what I was afraid of and never tried one... Personally don't like fiddling around, I like setting the nocking point and leaving it, although periodically checking it for movement, but don't like tinkering with nocking points unless I absolutely have too if for somehow got moved for whatever reason (string stretch, slippage or such)...
Thanks for the info though folks...
