RE: fall-away or whisker biscuit?
Well I just went through the transition that you are going through. First, let me say that both types of rests are great. I just bought a QAD Ultra Hunter last week and installed it very easily and had it tuned within minutes. They are very inexpensive also. On the other hand, WB's are a very reliable rest. You don't have to worry much about them. What can go wrong with it. Sure in time they wear on your fletching and the brushes wear out, but they are a very consistent rest. I like both, you can't go wrong.
