I love SRT RADS climbing, it's my favorite way to climb a tree hands down. I do it just for fun. But a throwball is intractable when I rarely hunt presets, so it's not even an option 95% of the time. If you hunt mostly presets, can't recommend enough.
I really wanted to love Stepps, but I just couldn't get there. Too touchy to get them set on trees with thick bark like chestnut oak. I also just don't feel super comfortable with any single foot climbing method including bolts.
Currently one-sticking which my own technique kinda borrows from RADS a bit. I used three sticks for years before going to one. No problem using three sticks, just nice carrying two less.
Sticks just work. I can also 2TC, but I just don't quite love it yet. I might get there eventually with some tweaks to my system that make moving tethers less finicky. That's my current hangup and also want to try the double foot stirrups vs the leg wrap. It's on my offseason list.
Plan on going back to a climber at least part time when some of these new options come out. Nothing is faster or easier, I miss it when I want to be ultra streamlined, ninja speed run and gun.
