I have a viper that's about 5 years old now. It's really comfortable but it doesn't see much use because it's so damn loud and bulky. Didn't use it at all this year in fact. 100% of my hunts were run and gun hang and hunts from my Lone Wolf Assault and 4 sticks. Gave it a look over prior to the season. All looked good except for the cables which the rubber coating on them gets pretty beat up after a season of use. The cables are otherwise fine and I've gotten tired of replacing them under the guise of making this already egregiously loud stand "quiet". So I roll with most of the rubber pealed off the cables now.
Ive used climbers for years, most of the time alone and always a few miles into the woods. Never had an issue other than wet mossy tree slippage. Although I run it through a thorough inspection each spring before the season comes around
