I have been using a Ripcord Ace but had nothing but problems with it. It finally gave up the ghost and I bought a new rest that appeared to be well designed and rugged. Turned it would tune so I went with a whisker biscuit. So far it seems to be as accurate as any fall away I\'ve shot and the containment is obviously hard to beat. As of now I don\'t see any drawback to it. For those that have experience with them are there things I should be aware of such as weather conditions or bristles wearing out. I do shoot quite a bit.
