The Back of The Hand was one of my first climbs at the Pinns, back in the late '70s. Nice to hear the bolts have been replaced ;-)
I wasn't leading back then, but I do remember that belay knob, so cool Atomizer, that you hit that thing.
Carpel Tunnel is scary if you don't stem. I was trying to impress some gal once and thought I'd look cool if I did it straight up. That is one awesome route! Funny, but if you rap from above Carpel, you only need a 60m. I always forget and end up downclimbing part of Life Line, ha.
Indeed, The Hand is a monument unto itself.
