I use the Treesuit and find it to be comfortable, stealthy, and versatile. Takes longer to strap in than my lone wolf climber, unless I have a climbing systom in place. I'm still looking for that fast and easy portable climbing system; tried LW sticks, Stepp Ladder, Ameristep strap ons.
So far I have settled on Sportclimbers spurs for compactness and light weight, when going into an unknown area. I use screw in steps for my repeat setups, but had 5 steps removed and my haul line cut last weekend...
