35 yrs bow hunting I have played with a lot of different set ups
here is my 2 cents
YES you can shoot mechanical's with your set up, the ONLY true advantage I find with Fixed blade heads is,once there in the animal, they stay as is, and can cut and cause more damage and or pain, making an animal NOT want to MAYBE walk away as far
but the fact is real simple, if either head doesn;t hit a vital, its a HARD deer to recover IF at all
I personally have better luck with expandable and less tuning issue's to get them to fly as my field tips do
there is NO magic broadhead out there that will get you a kill if you DON"T put it in the right spot (vitals)
the larger the cut, they more energy it takes away at impact! when they expand
so keep that in mind!
