RE: A have some questions about the Summit Revolution.
I gotta agree with Frank:
1. yes
2. ye
3. yes
4. not too heavy
5. yes
6. revoution
I also own a viper and love that stand. For me though, the Revolutio wins because it is more comfortable. The Viper is also very comfortable, but the Revolution is jut a tad bit more comfortable.
As far as using it as a stand up sit down type climber, I can not get the hang of the Revolution to use it that way. I use it as a hand climber and go.
