I've been having fits the past 2 weeks trying to find an elevated rest that works for me. I got a Black Bear WARF and wanted to give an elevated rest an honest try. Tried Bear weather rest first...tuned bare shafts for it and they flew great. Exact same fletched shafts flew like crap.
Next, tried a compound style, overdraw type rest that bolts to the other side of the riser and the arrow sits on two little prongs...hated that. Made 2 shots and pulled it back off.
Next, tried a cheap plastic threaded rest. Arrows flew great but they were way too far above my hand. Couldn't get my brain to readjust.
Finally scrapped all of that and put a small metal rod under Velcro for the shelf, a thin leather strike plate on the side with a furniture pad to build it out. Same arrows that I cut for the weather rest are flying great now. And the arrow is where it's supposed to be in my sight picture.
