You act ass if fixed blades have never broken inside of and animal before. Mechanicals are new and they scare people, but as the years pass they are going to get better and better. It is like the switch to carbon arrows people had these same kinds of arguments. I personally see a complete pass throug a waste of energy. I have taken a lot of physics classes in college, and know that a arrow flying through animal and sticking in the ground is a waste. You want all the KE to transfer to your target thus giveing a more effective and humane kill. I personnaly do this through mechanical arrows. Others can get bigger arrows, but My ultimate goal is for my arrow to create and exit hole but stay in the animal or fall/be pulled out by the animal.
