I tried a friends Summit Viper 2-pc climber one day.

I thought "How in hell would I get this thing all set up, climb a tree in the dark and while doing that inch up the safety belt as well?" It was the scariest thing I ever did - and carrying that thing on my back was like toting my living room Lazy Boy with me - not to mention my bow as well.

Screw that I said! I use ground blinds. Like I said - cost me a whopping $16 for my ground blind material.
