Maybe I'll sell you the ones off the new set I just picked up. I don't like them near as much as I thought I would (the suction cups that is. The sticks I love).
They don't attach or hold quite as tight as demonstrated in the ATA video. Lots of wobble and forces the sticks wider apart than they need to be. I might remove mine and go with
@DaveT1963 exercise pad mod with bungie's (which didn't come with set as advertised). One of the major benefits of this climbing system is how compact they pack.
