In reply to Scrambletastic:
I think the general answer is, it depends. Unhelpful I know, but true.
For example, I've done Corvus in the rain and Pinnacle Ridge on St Sunday Crag in snow and ice and found neither of them too troubling. Your view may, quite reasonably, differ. I wouldn't choose to do Giant's Crawl in the rain; it's polished, so will be slippy, and I thought the belays not too good on the slab, though this was of academic interest at the time as I climbed it in alpine style on a rope of three so we weren't setting anything up.
Way back in the pre-internet age we used to talk about getting to know a guidebook; knowing what you could trust, which phrases were hiding something and what was meant by different terms used by different guidebook writers; 'exposed','interesting', 'gymnastic' and 'puzzling' were all words that implied a lot more than they said. You may find that as you try things out, you progress up a similar learning curve with the books you have.
Good luck.
