hahaha, I dunno, one of the apes.
Seriously, I don't have long arms. I put the top section down as close to the platform as I can with interfering with me pulling the cable out and adjusting. Adjust it and then pull the top section back up to where I want it.
Of course, I did do this a lot while climbing, not at height. Once I realize the platform isn't going to be right, I'd rather adjust it at 10ft up a tree than 20ft.
I haven't had to do this yet with my LW Sit and climb. But absolutely, the two tethers on both sides really makes me feel more comfortable about performing that manuever.
