I'm sure Len will tell you there are too many variables to give you the correct answer in cyber space. If you check and it's not arrow specific it would depend on HOW BAD the every other arrow was. And YES, a fall away rest will help with flyers as they eliminate arrow contact with the rest. Form flaws will be exaggerated with a shoot through and be more evident down range. A little heel, death grip on the bowor too much palm is transferred straight to the arrow. I'm not a fan of the Quicktunes. I bought one of their top of the line Micro adjustable rest 4 years ago or was it 5 years ago. Anyway, things were inconsistant. I was pulling my hair out and took it to Len. He got checking it out and found that it didn't always return to the full upright position. He called Quicktune and they said, no...don't take it apart, send it back to us. We did. I got it back about 3 weeks later. Shot it a couple days and the same thing started. Sent it back. They sent it back and said it was fine. It wasn't. The spring was just not doing the job. Len put a line on the riser even with the top of the arrow. One arrow it would be up to the line, the next it woud be an 1/8 of an inch under the line. It was finicky. Sometimes it would hold the arrow up and the next time not. I wrote Quicktune and told them they were wrong but it was OK as I threw the expensive POS in the trash can and put on a Muzzy Zero....end of problems. And aren't you proud of me for not mentioning the obvious cause for your "BOW" not shooting consistant. LOL I'm not even going to mention loose tolerances at the pivot point. [8D]
