I prefer to use a mechanical broadhead. It is my personal choice. I use it because when you hit yourtarget it slows down your arrow while it passes through, if it passes through. the slower it goes through the more it tears up on the inside. I actually have had 4 arrows not pass through and had the deer run less than 40 yards and drop. I think that when the arrow stops on the inside it really damages the internal organs and doesn't allow a deer to clot and get away.Mechanicals shouldn't affect he spin on the arrow as much as a fixed blade would, here you already have your flections/feathers turning your arrow for you. I wouldn't want to have a fixed blade making my arrow spin differently than I am used to with my field points. But again, this is just my personal beliefs and opinions, It all comes down to a personal preference, as with any Archery product. If it kills a deer, then it works. Good luck hunting.
