From what I've seen, several mechanicals have poor blades and are also prone to problems with deflection on steep angled treestandor quartering shots. One more thing that sets the Grim Reaper apart from the rest is they have a patented inner spring mechanism that allows the blades to float independently from eachother which prevents deflection on angledshots.

Bottom line is thatwe owe it to the animals we hunt to shoot what we're most confident with; however, sometimes we are confident with less effective equiptment than is out there! For instance, I had a guy try to sell me on the Rocket Hammerheads because he had used them for years, and they have a 2" cutting diameter. But if you look at the tests done by Grim Reaper, the Hammerhead blades are mangled after shootingthrough the deer shoulder/ballistic gellatin! The Grim Reaper blades were still in tact after nearlypassing through a steel drum!!!

Watch the videos.... the proof is in the pudding or in this case the ballistic gellatin!
