Treebeard, have you seen the bullhead broadheads? They are like the guillotine, but better (IMO). They are stronger, fly better, and a lifetime warranty on the heads. If your sighting in and you skip one across the dirt and bent a blade...just send it in for a replacement. Here is a link:

The one thing I will warn you about with those types of broadheads (guillotine or bullhead) is you HAVE to hit them in the head. My buddy and I both use them and we typically video our hunts too. Here is a little video of a hunt of mine last year. You can also see the how the birds interact with our decoys and you can also see when you are just an inch too low with those types of heads.

It is such a blast, I can't wait for spring season to roll around. Behind bowhunting the rut, this is next best I think. Good luck
And welcome tankdogg, good luck this weekend.
