I've been using Slick Tricks for the last few years and had very good results. But, like so many others, I'm still curious about the new and improved stuff. So, a couple of years ago, I tried Rages. Maybe they are great, but not for me. And I found changing the blades is impossible for a guy with big fingers. This year I shot my first deer with a Kill Zone. A good hit and the deer died within 40 yards. Truth is, any broadhead would have killed that deer where I hit it. A shot at another deer went into the dirt (don't ask) so I bought replacement blades. I changed the blades in 5 minutes, including the coc tip with no cuts on my fingers. My son has shot two deer with Kill Zones and been very happy with the results.
