Today's broadhead designs are light years ahead of what we had to choose from 20 years ago. If you put any of today's broadheads where you are supposed too, the result will be a dead deer. Most of the lost deer reports we hear about that say "I hit the deer perfect but the broadhead failed" are the result of the hit not being where the archer thought it was.
I always tell folks, if your modern broadhead of choice shoots great groups, hunt with it. If you like mechanicals, opt for the "crossbow" version as they often have stronger retention systems. If you like fixed blades, usually the regular version and crossbow version are exactly the same.
It was good that you replaced the string and cables on it. Make sure the cam timing is good after the string and cable change. Respect the danger of getting your fingers where they should not be. Always keep them below the rail. Load an arrow from the front, not at the mid shaft, which puts your fingers in the triangle of danger. If not using a rest, choose carefully when to bring the bow to the shoulder if a deer is approaching. Your forward arm will not last long and you will have to lower it down if the shot doesn't come fast. I have been busted many times getting caught in that scenario.
A crossbow is still a bow and kills by bleeding. Choose your shots wisely.
I support all hunters, regardless of weapon or technique!
