I ahve have experience with good ones and bad ones. The last experience I can remember was when a guy tried to sell em a drop away rest and kinda snarled his nose at what I wanted (Wisker Biscuit). He kept telling me all of the flaws he found in them and why he did not shoot them. I, being the a$$ that I am gave him my opinion and told him to put the rest that I wanted on the bow.
He seemed to get a little nicer after that. I hate it when these guystry tell you what the latest and greatest things are just because they are popular right now and everyone is using them...
