Mechanical
why use fixed you get a smaller diameter hole with fixed and if you get the right mechanical you dont lose much penitration and they wont deflect. sharpness is key. I shoot 60 lbs and get clean pass throughs with mecanicals and have even shot a deer in the spine and it penetrated and paralized it. The shot was intentional it was straight under my stand so i shot their knowing if i missed it would still go into the heart.
