I have the sit and climb and I have the assault with 4 sticks. I love them both. The climber is definitly the more comfortable of the two, however you are limited as to what trees you can set up in. It depends on the areas you plan on hunting. Don't worry about stability with the climber either, it is rock solid once you sinch the seat to the platform.

I would probably pick the assault and some sticks if I were you though. With the hang on you don't have to worry about finding a climbable tree when you find the spot you want to sit. JMO.

Also, the assault is very light and easy to set up, but once you strap 4 sticks on there it weighs about the same as the sit and climb when on your back.
