RE: NAP Spitfire Mechanical Broadheads
I have tried these and I agree with 5 shot they are slow opening. I also found they penetrated very bad....just my experience and after a couple of actual tests on game. Some people love them and have had great luck, I say try them and see how they work for you. I actually like the NAP shockwave much better. I myself am a big fan of the Reaper/Hammerhead & the demon/steelhead mechanical broadheads. for those who don't know the Reaper & Demon are Golden Keys head that are made for them by Rocket. They are some of the best performing mechanicals I have ever seen.
