I have a Summit Viper, and I can attest to what GARedfish is saying. Summit climbers are BY FAR the BEST climbers I have ever owned. Fairly light, comfy, quality built and backed up by a company that really does give a hoot about its customers. Stacks together tight so you can carry it into your favorite spot, and comes apart easy when it is time to move. Very easy to get replacement parts too. Highly recommended if you are looking for a climber that will not let you down. I'd be all over it.
