ha-ha! A fraction of a second ago I fell off the overhang, hence the expression on my snout...
This Grivel tool is ingenious! It gives so much flexibility on technical climbs; I love it... Of course, it's leashless, and there is this great debate about leashless tools on alpine routes (not just short technical ice/mixed routes); BUT, I am contemplating adapting the tool for alpine by attaching a removable leash (sort of like on the Cobra tool). If you know of successful modifications of this sort, please let me know..
I'm sure the regular BD android leash would work (not the viper android), though have heard about them accidentally unclipping when mantling ... kind of a scary thought for alpine stuff. I suspect that a leash like the BD lockdown or grivel easy-g or whatever would probably work too, but of course wouldn't be as easily removable.
I like the petzl clipper that came on the quarks this year, but I don't think they make a version that clamps on like the BD android - have to have a pre-drilled hole in the shaft for the quick-release post.
