Alright here's the deal. I have a Summit viper climber and love it. I need a good hang on stand that is comfortable enough to sit all day. I also don't want a little tiny seat like the baby gorilla, or a little tiny platform. I'm not too terribly worried about the cost and wieght isn't my biggest concern either.
Here is what I'm looking for:

1. Comfortable
2. Large Seat, Platform
3. Quiet, solid construction

Any suggestions?
