I have a summit climber and my last one was a summit also. I have several summit fixed stands also. I have to say though that I saw these stands at a show recently and I was thoroughly impressed!!! When I am ready I will definitely look hard at these. They are lighter I believe than the summit viper and are rated for 300 pounds. They nest in to each other for carrying/packing out. The seat was comfortable also and overall its a very versatile unit.
