I have the Viper and love it. I rest my bow and gun across the bar, I always stand when I shoot my bow so the bar isnt a problem. I have a small pack that I attach to the bar for calls, binoculars, drinks...etc. I always use a full body safety harness in it. I seem to nod off in it so I need to make it not so comfortable.
I just taught someone how to climb with it and let them borrow it last week. They shot 2 deer out of it.
