I can't recommend them either. My test results mirrored 5 shots.

I did take a decent buck with the head on one of my hunts this year and it did stay together albeit didn't hit any ribs. A double lung hit and the animal went around 110 yards with almost no blood trail. The wound channel reminded me more of a gun's than a bow due to the fact the hole was so small. In fairness to the head I should say that the hit was a little higher than I would have liked it to been.

I can guarantee you would never catch me hunting a grizzly with one.<img src=icon_smile_shock.gif border=0 align=middle><img src=icon_smile_dead.gif border=0 align=middle>Until they make the head more reliable I wouldn't hunt anything bigger than a deer with it.
