This past weekend I was playing around and decided to one stick climb with just a HSS vest.I always keep a lineman's rope attached so I just shortened it with the prussic to make a bridge.Shockingly it was easier to climb with than a JX3 or a regular saddle.Once I got up the tree,I adjusted the tether and leaned back.Again,I was shocked at how comfortable it actually was because you actually get some back support.All it need was some support for my butt and then I remembered I had a sit and drag at home that I never used.I removed the straps and just clipped the seat portion to carabiners where the bridge hooked to the lineman's loops.When you lean back,it's extremely easy to adjust the seat to the perfect spot.Honestly,it was the most comfortable saddle set-up I've ever used.Another advantage is the vest has pockets and it's way easier to wear walking in than a traditional saddle.
