has anyone used this rest if so can you tell me if its a good rest or if there's any fletching clearance problems
It can be a pretty good rest, I shot one for many years. Never had any problems with mine. NAP Capture 360 or Wisker Bisket IMO would be a better choice. There are several "full containment" rest out there that you may want to check out.
I have had the pronghorn on one of my compounds for many years and it works flawlwssly. I would recommend it to anybody. Stay away from the toilet brush rests as mentioned above.:D
