I have owned several climbers from different manufacturers and I have to say that I am the most pleased with both the Summit Viper and the Cobra. I plan on using the latter tomorrow afternoon (if it doesn't rain) for our season opener here in PA. Both stands are relatively quiet, easy to use and extremely comfortable. Overall weight is on the low end of the mid range compared to what is on the market today. Probably the only aspect I would improve is what was previously mentioned....their packability.
