Fixed blades all the way. I have used muzzy mx-4s, crimson talons, rocky mountains, and eastmans, all fixed blade,and they all work great for deer sized game. My broadheads shoot the same as my field points. I think that if any bow is tuned, they should shoot the same, but maybe my bow setup just shoots them the same. I've tried expandables on hogs and didn't get penetration like a fixed blade (shooting 70 lbs) and the blades bend/break easily.
