Climbing with a platform is like one sticking... reach waaaaay up high and attach your platform, put foot in aider and ascend, tether in and reach below/behind you to remove your platform, reach waaaaay up high again.Platform climbing no good?
Edit: I mean't why 2TC and not platform climb. Which is better and why?
2TC is smaller movements (18-20ish inches) and everything is directly in front of you in the waist to top of your head area. No need to contort your body or reach behind you.
