I was thinking the same thing about the fletching contact. Looks like this could be a serious problem on some bows. Also I am not sure I want my cables constantly banging and rubbing into that rubber thingy. I have read a lot of posts with folks shouting its praises but never fron anyone that had actually even shot it. I think I will stick with my NAP Quicktune. Works perfectly with less unnecessary gizmos and bulkiness. I could be wrong, but I don't see this one making much headway personally although marketing overload has done some amazing things in the past.
