Impossible to say with the information given. How much weight are you shooting, how long is your arrow, how heavy are the arrows you are shooting and at what speed? In other words what is the kenetic energy of your arrow at your maximum shooting range. I can make this recommendation if you are shooting turkeys, rabbits, and deer at close range a mechanical probably has a great advantage. I also believe that if you are shooting Deer at ranges of 30 yds on out or Large animals like Elk, Moose, Bear, Hogs you should probably use a good flying fixed blade head personally the muzzy 100 or 125's are a great head.
