I put a set of diamond back rattler on one of my bows today, and I can see what you mean. Once the snake is trimmed to fit the limb, there is very very little weight added to the working portion of a limb, and I don't think I would lose more than 1 or 2 fps with any skin...so, it really doesn't matter to me anymore if I was to have python, bullsnake, a watersnake, or whatever...as long as it is something I think looks cool.
