In reply to psychs:
Get back on there and have fun.
I had a double whammy on my left arm (cancer in 1990 - load of muscle removed and important nerve cut & ATB accident in 200? - nasty collarbone break) so it is now pretty f*cked . However I still earn a living as a mountain instructor - go to Awesome Walls on a semi rewgular basis to0 train really really hard to be a mediocre climber and still get on on routes regularly and enjoy myself.
Whatever you injury - you will find that you adapt your climbing style to compensate.
Dont beat yourself up too much about grades - just get back on the rock/plastic and have fun.
The biggest disability to climbing that I know in people is where their head is at - I know some relatively fit people whose attitude is their biggest disability - if you want to climb with a gammy arm - you will do so and enjoy it.
Perhaps we could link up at awesome - we should have one decent set of arms between us
Have fun
David
