I have to hostage pro rest, and so far no complaints but the brushes do wear. The brushes will start to wear after about 300 shots throwing off your sights. It does not mess up the fletchings at all. Also and old trick is to get a lighter and heat the fletchings up, they somehow straighten right up, but as long as u dont burn them everything should be alright. Ive done this a number of times and seems to do the trick.
