Ditto!!! I have a two year old Viper and it's just dandy. Especially with the newly added stirrups. I wouldn't go so far as to say it's comfy all day. I spent 12 hours a day in mine in Illinois two years ago and my butt did get sore, but hey, that's a long time and I have to sit most of the time due to a bad back. The stability of the stand is unparalleled. And it's very quiet if you learn to take your time and control it.
