RE: Fred Bear Vapor 300
I think it is a very decent bow for the price. My only complaint would be the low mount cable guard. Almost all of the traditional style single cam bows have gone to a high mount cable guard as the low mount version creates excessive stress on the single cam due to the hard cable/return string angle.
I would check out the Rackmaster as a viable alternative. In the same price range but with a high mount cable guard and a much nicer grip.
