> Give it a go, they should learn sometime. I know people that have been leading since the first day of climbing. Drop the grade until you can solo it and they are happy, focus on the technical issues of gear placement, belay building and rope management instead of the climbing challenge, score all their gear out of ten and show them how it could be better.
All this ^^
I've been involved in getting some people climbing this year and some have gone from never touching a climbing wall to leading grit diffs in a relatively short time - and this isn't gung-ho youngsters, more the nervous and mature types.
Getting them leading in a safe environment as soon as possible means they'll understand the whole system better. Very easy routes, stuff they can walk up, or even leading with a top rope (although that needs an extra person) are perfect for initially learning the technicalities without the distraction of the climbing. And not being afraid to spend time doing and redoing stuff (especially belays) until they're comfortable will pay dividends, rather than relying on picking it up as they go along.
I think my instruction before seconding on multi-pitch stuff amounted to "You tie a prusik like this, and don't touch the fig-8 after abbing - it'll be bloody hot"
If they get some basic leading skills (even if they don't use them on this trip) the stuff they do need to know will make more sense.. belays (and escaping them), prusiking, abseiling (including anchors and joining knots).
Is it too late to get them a good rope techniques book for Christmas?
