The only mechanical head I trust is swhackers. I see lots of benefits, they don't waste a bunch of energy trying to punch a 2" entry hole, the blades are still razor sharp to slice all the important stuff, and they really truly do fly like field points. I've shot a few deer and have had nothing but great results. And all pass through. I still don't understand why rage, etc. Are still making heads that have to waste so much energy cutting a huge entry hole so your chance of a pass through goes down substantially and your blades that just had to punch through ribs now have to cut organs/arteries. You only get a set amount of kinetic energy when the arrow leaves your bow to get the job done and have enough left to punch an exit hole. I always want an exit hole, it's always lower on the deer than the high entry hole (I hunt from trees) and really helps tracking
If I wasn't shooting swhackers I'd personally use a single bevel fixed blade. I just spend a month or two practicing before the season and really don't want to take anymore time to have to tune broadheads and all that.
