I just purchased a broadhead backpacker. Setup it's the same as the Viper but with no front rail. I shoot sitting down quite a bit so I didn't want the rail. The broadhead does take a bit more to set up as there is two bolts to assemble every time. The other concern I had with the viper is the size when it's packed together. I usually travel with an ATV in my pickup bed so there is no room to put a stand there. The viper would never fit in the back seat of my truck with all my gear. Some thing else to think about.
