I thought the whole reason the rope wrench was invented is because the usual friction devices wouldn't work properly in SRT without something like the RW to add friction?About the ZZ alone in SRT, It works well for me. I use it all the time on my secondary climb line (66'). It doesn't lock in the descent and it's even a bit touchy. The Akimbo is on my main line (130'). Both are used at will in SRT and DRT mode, up and down, sideway too.
@flushcut , I'll check out the gri gri. For taking big falls, rock ropes and gear is a must but the falls I'm envisioning with top rope solo are in the 1 or maybe 2 foot range at most.
