I had the summit viper and it was comfortable but my Knees would hit the bar. I bought the revolution this year and it seems to be the ticket. I'm 6'2" and you can kick back in this lay your feet on the bar plus with the way it is laid out it I leave my bottom platform down a little farther than I did with the viper and you can just roll your butt and you in a standing position with out a lot of movement.
