if you want a tough broadhead, i would look into the abowyer broadheads. recently i was at batmans place doing some shooting. he let me try out some carbons, some with feild points and one with the abowyer broadhead. im not sure what the weight is up front of his arrows are . when i shot the broad head tipped arrow, i totally missed the target, distance was about 20 yrds. the broadhead completely penetrated a 2x4 at 20 yrds with no ill effects, it wasnt the goal of the shooting session, but i was impressed none the less. ive never seen a zwickey survive that. i dont have a pic to prove it . just ask anyone who shoots with abowyers and they will tell ya, ruddy
