I'm thinking about fixing up an old(very old) bear compound bow. It needs a new arrow rest, and I'm wondering what would be quiet, small(so it won't catch on brush), and simple. I don't want anything that will obstruct my view of the arrow because I like to shoot instinctivly. I'm new to compound shooting. Should I get heavier arrows because it shoots so slow to give it some extra momentum? Or lighter ones to get extra speed?
