I made a platform that I use as a 1stick. Put a cheap Amazon cam cleat on it, rated at 300lb?? Looks like the weak link is the tiny bolts. I drilled a hole in one cleat, put a small bolt through from under it, put a rubber well nut on the bolt finger tight, and then a nut on it to lock the well nut and nut together. I use that as a way to open the cleat to get rope out. I used amsteel full bury 1/4 inch I think. Its thicker when they run it back through the rope. From hang free.
Just hang, put my foot under top brace on platform, end of rope in my hand and feel for the well nut, move it and platform is free.
I'm new, but this is the easiest way I have tried to climb, with the lightest and least fiddling.
