I have decided to try the NAP killzone maxx broadheads this year. 2 3/8 cutting diameter and I am happy to say I am BLOWN away with how amazing this broadheads are. Great quality reliable and lethal. I have killed a 3x3 blacktail this year at 49 yards complete pass through sprinted 30-40 yards and hit the dirt. I killed a coyote that made it 7 yards with a gut shot at 27 yards. My buddy killed a bear with a NECK shot, bear made it about 500 yards and after a long recovery time we found him. But it still slit an almost 2.5 inch hole though his neck and throat that drained him. And I also arrowed (bear post is also in the bear hunting section) an estimated 486 pound black bear a few days ago at 18 yards. Double lung perfect pass through and that bear was dead at a 40 yard sprint and probably 20 seconds. Amazing broadheads and would definitely recommend.
