In reply to An Triubhas:
I found the transition from indoor to outdoor quite interesting.
I spent the winter indoors, climbing regularly to work on basic movement, strength and rope skills. Top roping to 6c and leading 6a is generally quite consistent for me, and usually depends only on how fit I'm feeling that day!
However, when I moved on to trad, initially there were a hundred different factors which affected the level at which I could climb that day:
how nervous I was (the night before, the drive to the crag, at the bottom of the crag)
the weather
the condition of the rock (dirty, slimy?)
how well my last pitch/route had gone
the exposure and psychological impact of gear placements (for example the second pitch of The Flying Dutchman at Polldubh (S), although has good feet, the traverse is exposed and the prospect of a wee swing back into the corner is quite a load on the mind of a novice like myself, so it felt much "harder" than a severe, although the moves were actually rather simple)
how much confidence my partner has instilled in me that day (whether by encouragement, advice or generally making me feel well looked after)
Etc etc
Basically, that's a long winded way of me saying that I can't lead consistently at any grade outdoors! Whereas I generally know what I can and can't do indoors quite specifically.
That said, I'd rather be shaking like a dogs leg on Severe outdoors than cruising 6's indoors.
