imo, fixed blades have less of a chance of something going wrong when that big monster buck comes in at twenty yards, i shoot wasp boss bullit broadheads 100 gr. and with my hoyt cam and 1/2 i dont have any flight problems, in fact they shoot pretty damn close the same as my field points, and i think thats good for a fixed blade. i'm very happy i with the wasp bullit's but you should go to your local pro shop and ask around and see what would be best for your setup. anyways i think fixed are the way to go because if you make a good shot you know its going to get the job done at any angle.
