Great heads and they work well for me, I would be careful and not take any sharp angled shots with any mechanical heads, they may have a chance to deflect. Keep your shots yardage close and you will have one of the most awesome blood trails you have ever seen.
A friend of mine uses my bow and with all four deer shot last year, the blood trails where huge and my friend shot both of his deer at 5 steps on the ground and both of mine were 8 steps on the ground. My friends first deer ran 10-15 yards and the second deer he shot just beside the neck and the arrow went all the way through the deer and it dropped where he shot.

I shoot a PSE Thundercloud @ 65 pound draw.
