In reply to Robert Durran:
> I wonder if you have to do all the pitches in the correct order.
My (limited) understanding is that, by the local standards, no you don't have to do all the pitches in the correct order in order to be considered to have freed the route, or even freed it ground-up (because ground-up really just means haven't abbed in before). Though generally you would do, because you come across them in that order...
Tends to be the hard pitches that are the exception, for example in this video I think they go down to work the boulder problem having already made it to 'The Block', which is a bivi site above the Boulder Problem/Teflon Corner. The BP/TC and The Block are separated by one 5.10 pitch, which they freed before they attempted the boulder problem free. They didn't manage to free the boulder problem in this instance, but if they had done I don't know whether they would have 're-freed' the 5.10 pitch or just jugged back up their fixed line (think they had one).
As far as I can tell, big wall free climbing lost any semblance of a rigid rule set very early on when someone (I forget who) doing an early repeat of the free Salathe decided to have their portaledge above the headwall pitch which they were working on, rather than below it.
> In fact could you just frig the whole route and then climb it top down (so to speak), with all the hauling and aiding out of the way and top-roping always convenient?
Despite what I said above about no semblance of a rule set, I suspect that this would be pushing things a bit!
