I was shooting a Viper Predator Microtune when I won the IBO Worlds a few years ago. I absolutely loved that sight, and shot it so well. Had all the fibers swapped out for 3ft .019 green ones, that I didnt melt the ends on, man that thing was awesome. Knocked my bow out of the tree on a late season Wisconsin hunt after killing the buck in my avatar while trying to climb down and drag him under the tree so I could keep hunting. That Viper snapped right off when the bow hit the ground. Drug the buck under the tree, climbed back up, and drilled a doe at 15 yards without a sight. Anchor and shoot. Thats when I bought the armortech, and although I didnt shoot it quite as well as the Viper for some reason, probably because of not all green pins, I won quite a few shoots with it, and the adjustments were far better than the armortech. I recently got a really great deal on a sureloc lethal weapon. That was a pretty awesome sight too. Sold it again not too long ago though. The new lethal weapons are as good as it gets, but $400 just isnt doing it for me...
