In reply to GrahamD:
Thanks all. The arm-span seems like a decent rough guide, thanks Webster. Sure I enjoy the day out regardless and as a noob all experience is good experience, but I like to know where I am in ability / progression - for me improvement / achievement is a big part of the satisfaction in any sport, especially one where you're only competing against yourself!
I'd rather dog a route and come back to it another day than cheat for the sake of a tick - but to me there's an (unavoidable) grey area. Any climb can be made harder by seeking out moves with fewer / worse holds. I presume routes are graded based on the easiest way up them within the limits of the line. I guess I'm trying to define the area within which that easiest route may lie.
When you say 'pure', do you mean following the general direction/flow of the climb? Of my two tenuous ones, I would say in one case I did: though there was certainly a harder move to be made (I'm only climbing in the 5s at the moment but it's all relative) slightly left, the easier option was a similar distance slightly right and both required a bit of divergence. The other maybe I should have another go at, as I hit an overhang with a break below whilst left of the bolts and made a deliberate traverse of maybe 1.5m to the right side of the bolts to tackle a less severe version of it. This one also had an easier line close on that right side, and the area I climbed was probably halfway between the two, hence not sure I haven't skirted the crux (and on your basis of feeling whether you've done it pure, I guess if I'm doubting it the answer is probably no!).
