In reply to Mr Fuller:
> Is it just technique?
Quite possibly. I used to get loads of finger 'tweaks' but touch-wood I've not had a bad one for years despite being fatter and climbing harder than ever. Chances are I've just learned the warning signs over the years and being a bit less obsessed than I once was I rest any niggles as and when they need it.
> As an aside, how good an idea is strengthening my fingers on a fingerboard? I know they’ve a reputation for causing injuries if used incorrectly, so could these make things worse?
Used carefully there's no reason why a finger board should hurt you worse than bouldering, in many ways it's more controlled. The problem I have with them is getting a decent warm-up and getting the intensity right (I'm weak and realistically require assistance). My other problem is the recovery time from a fingerboard session is unpredictable, sometimes it eats into climbing opportunities which is just plain stupid.
