I have a metal Sky archery ILF riser that is giving me fits. The shelf is flat with a slight hump to get the arrow up off the flat shelf. I'm shooting a fixed crawl, so my nocking point is kind of high. When I have the nock point up where it needs to be, the arrow touches the front of the shelf. When I move it down, the arrow bounces off the back of the shelf and the fletch digs into my hand. I have not been able to find a sweet spot. I think I'm doomed to putting an elevated rest on it, but wanted to see if anyone else had any ideas first. Thanks.
