In reply to Route Adjuster:
Thanks, I'll look at my grip when I go again - I went this morning but the place was packed with a party or something so I didn't bother, Monday's likely to be the next chance I get so my hands'll get a breather I guess.
I've been putting a lot of thought into footwork recently, following the book; "The self coached climber" by Dan Hague and Douglas Hunter. I'm working with the silent feet, backwards traverse and same side in traverse exercises (I've no idea if these are well known or not), the general thing is keeping hips in to the wall, moving the arm closest to the wall and controlling my centre of gravity - so the hands have been a little neglected up to now and you may be on to something.
Tape - I tend to avoid this sort of thing because I generally find I'm better off without but that's not to say I'm not willing to try. I have some micropore tape (the papery sort), will it do the job? Any advice where to tape?
