Wondering if its a bad idea to use the hand ascender with a small sling to advance the rope wrench. Haven't come across any info on it so wasn't sure.
I use a frog walker system with neck bungie to advance it currently.

I know a couple climbers who use the Kong Futura to advance the wrench. Been a few posts showing how people take the safety lock off the Futura cam so it's easy-on, easy-off for wrenching.
I think it's a reasonable and safe way to advance the wrench, it would drive me crazy though to have to move it up by hand except for maybe a really long straight up ascent.
