In reply to chris smith:
The ideal MIA registration will show multi-pitch routes from all over the UK, with sea-cliffs and full-scale mountain routes being well represented. Fionn Buttress on Carnmore crag is given as an example on your registration paper and is an exemplar of a good route to have listed; it's big, remote, solid at the grade, there are traverses and route-finding to think about and in parts it may be loose or dirty. Other top picks would be something like South Face Direct on Chair Ladder (tidal access and sea-state considerations), routes on Cloggy or Scafell (moody atmosphere, could be hell on earth if conditions not judged well) or something on an rarely-trod cliff like Foinaven or Marsco (shows an exploratory understanding).
What will definately under-sell your registration is an imbalance of shortish routes at roadside multi-pitch venues like Raven, Shepherds, the Pass, Glen Nevis, etc. I did put Valkyrie at the Roaches on my list, but only to show a diversity of experience; the suggestion (cant remember if this is stated or not?) is that 2/3 of your routes are on serious mountain or sea-cliff terrain.
