I am the furthest thing from a equipment or brand honk but damn man NAP Killzones are amazing. I know today there are dozens of heads that are more than lethal but I use these and all I can say is WOW do they fly true and do devastating damage. Bravo NAP for giving a 27” draw bowhunter a brutally lethal mechanical head. Never even bent over on my trail yesterday.
I've only killed 2 deer with the KZ, but had great blood trails on both. I've been alternating between the KZ Maxx and the Spitfire XXX on my hunts this year, and happened to have had the Spitfire on when I shot my buck last week. Nicely done.
