Was hoping to hear from someone who has used nap's spitfire mechanical heads on bear and what they thought of them? I used thunderheads about seven years ago and got a complete pass thru on a 240lb. bear.I am now soon heading out for another bear hunt and all I have are the spitfires.Should I spend another 30 bucks and get the thunderheads or will my spitfires that I use on deer do the trick? Thanks in advance...Hugh

Blew right through a bear w/ a spitfire. Arrow bounced off the ground on exit. Blood trail that couldn't be missed.

I have shot 3 black bear all with spitfires and all were pass throughs. All were recovered. None went more then 80 yards.

I hope i get equally good results with my hypershocks this season.
