I've had that harness for a long time but typically only use it in big mountains. I use the Flylite cocoon at Lookout or when towing as it is lighter.
Expect videos from Rick, Sam, or Charles as they got some huge flights in on multiple days and seemed to have stayed through Monday. Sparky should have some good pics too. It takes a while to learn what works at Mount 7 and often the lift is light and trashy, but they figured it out.
