I like my Summit Viper. I tried the Summit Cobra & BM, but noticed I could climb much quieter with the front bar. I'm in excellent shape, but just noticed it was easier to control the bottom platform if I was in a sitting position, rather than "hand climbing".

I also really liked the Warren & Sweat climber, the belt system I thought was actually better than the Summitt's cable. However, it also weighed about 6 pounds more than the Summit, a little on the heavy side if you hunt hillsides.

I have a friend with a Lone Wolf, and it also is a high-quality, quiet and superlite stand. It will just cost you ~$100 more than a Summit.

As for quieting your Summit, I contacted them direct about the stand making noise during transport. Run the green strap vertically (instead of horizontally as directed per instructions) around the platforms, and slide the cables ALL the way into the platforms, almost jamming them inside---and the noise will be gone.
