I have both, the original Hybrid barrel gun that was the test platform for the new comp design(same design as Shane's gun he shot at worlds), and the new shorter V8. The hybrid shoots very predictable and recoils into your hand about the same as a limited gun, the dot tracks reliably up at 1 o'clock and comes back to center very predictably. The V8 looks violent, but hits the hand very soft, and the dot never leaves the center of the glass, depending on your grip, if you do what you're supposed to do, it will come back right where it was when you broke the first shot.
Open is all about how the gun feels TO YOU. I wouldn't shoot anything but the V8 for USPSA/IPSC, but i like the hybrid for steel, because i can use the predictability to help move the gun and dot to the next target. Load development for both is key for how it feels as well. If you're anywhere near VA let me know, ill bring both to the range and you can try them out side by side with the two loads i use.
