great use of rack thingees, looks like it works well.
Your trip looks like it was bloody cold and damp (reminds me why I would never live in the UK!)
It also reminded me that my old mtn bike has been up and down areas like your trip, I bought it from my brother-in-law who brought it over to Canada when he moved here, but had done trips up Ben this and Ben that, but I cant recall them, being unfamiliar with the names.
