Last year I decided to upgrade to a QAD HDX arrow rest. I was very excited about shooting with zero interference, but after shooting for a while I noticed wear marks on my rest felt and became frustrated. I thought maybe I just needed to move the nocking point up, but after messing with it for a while I couldn't get it is clear. I was afraid the rest wasn't falling fast enough, so today I decided to take some slow motion video of it and the attached pictures are the result. It appears the arrow flexes all the way down to the shelf which would explain why the rest is wearing. My question is, is this a tuning issue or is the spine too flexible? I am shooting a 30.5" draw length 70# Diamond Outlaw. The Arrow is a Read Head Carbon Max2 with 350 spine. According to the charts I look up, that spine should be stiff enough. What do you guys think? Do you have any suggestions for a good arrow with a stiffer spine if you think that's what I need? Thank you!
