In reply to Quiddity:
Weird you should mention 9 out of 10 climbers, just before logging on here I was looking for a copy of the book (and spotted one had been sold on the FS sub-forum). Definitely something I'll be getting.
I'm REALLY bad at slopers which I'm practicing at the wall and on the fingerboard I have in the garage but they're not something I can practice on the rings (unless I'm missing something!)...
The rock rings are in such a more pleasant place to train though and I can just throw myself on them in the morning or before lunch or when I have any spare time at all. I tend to only use the fingerboard when I have a spare 30 mins (and only when it's not raining and cold!).
My arm strength is ok for the grade I'm climbing but it's definitely something I need to improve if I want to progress so thanks very much for the advice. I need to improve finger strength in general I think, I struggle to even stick on the 2 finger pockets for anything over 5 seconds (though that's partially because my knees are quite literally 2cm off the ground given the rings are a little low!).
