[QUOTE][What do you think works best mechanical or fixed blade broadheads I've used both and I've heard the arguements from both sides I want to hear everyone elses opinion and experiences. I now prefer fixed because they seem to to more damage when inside a running deer./QUOTE] IF you're arrows with fixed blade broadheads are staying inside, NOT PASSING THROUGH, a deer sized critter, then you'd best stick with fixed/COC broadheads because apparently you're setup isn't producing much KE to start with, and going to any of the mechs. would only make penetration worse.
I prefer COC broadheads. I always get complete pass throughs, even on elk, and that's what I prefer. I prefer to be able to locate my arrow after a shot and have a chance to determine how good the shot was from the evidence left on the shaft. And IMO, two holes are better than one!
