In my opinion, the most important thing is that your bow is well tuned to the arrows that you'll be using and that the broadheads hit right where you want them to. Plus, the better your arrows fly, the better your penetration will be.

Depending on what weight bow you are shooting, you probably won't have any problems sending an arrow clean through a deer, no matter what type of broadhead you're using, as long as your arrows are flying true. I like the Thunderhead 125s, I shot them for many years. Now I shoot 2 blade Zwickey Eskimos. As long as they are scary sharp, they'll do the job you want them to do.

I might suggest that you shoot nothing but broadheads from here on out until your hunting starts. It pays to know what you have to do to get the arrow to it's intended target under any shot situation that will arise. I shoot mine year round. Matter of fact, I rarely shoot field points unless I'm at the range, which doesn't allow broadhead use.

Good luck on your season.
