I've hunted out of Summits for the last 10-12yrs until this season.........All the way back to a model I'm sure you never heard of the "Sabre". [:-]
The viper is a great easy to climb with comfortable stand. Doesn't pack up all that neatly or compact.
The bar can be a hinderance for shorter bowhunters (Not me LOL)
It's super comfy and rock solid in the tree.

A little clinky, clanky setting up and packing up.

For bowhunting ONLY I wouldn't choose one, I'd opt for an open faced model but you could certainly do worse.
