I've used a Summit Viper for the last 4 years or so and I find it VERY hard to believe you guys are getting that thing off your back, around the tree (top and bottom) with trial and error to find the correctcable length, get your bow tied on, get your harnesssecured and tied to the tree, and then climb (with a harness ) 15 feet in a couple of minutes and do it quietly.Come on now! How about in the dark?
I would estimate a solid 20 minutes for myself. Those cables aren'tthat easy or quiet to use, you've got to make every move with those cables delibrately or your going to be banging away.
