Upper cam is moving fine. It's doing like in the video 2300 posts ago that you put up where it doesn't want to grab the rope. It will grab when there isn't any weight on the rope. When I'm climbing and come to a stop, all my weight on foot ascender rope is tight where akimbo is and I go to sit down it wants to slide down unless I lean back into my neck tether then it'll grab. Maybe the rope I'm using(kernmaster), little to small, it's newish? Had it set F,6. I said earlier this is my first mechanical so maybe it's just gonna take some getting use to.
