ANNOY DIDDY, BUY HAGLOFS!!!
Yes, great trip report, Jamie, apart from the comment about my age 
In revenge, I shall mention in more detail your shower... When we got back from the Slioch walk, we turned on the rubbish cylinder to heat up water for showers. Jamie and I decided we wouldn't bother to wait the hour or so for the water to heat up, and in any case there wouldn't be enough for the five of us. I graciously volunteered to let him have first dibs on the shower and he headed off to the bathroom.
He was back in the living room less than 5 minutes later, still minging and clearly unshowered, and confessed to his utter wimpishness: he had barely got under the shower and had recoiled at the coldness of the water, recoiled so violently, in fact, that he'd ran into the wall at the far end of the bath trying to get away from the shower head, before beating a cowardly retreat.
Perhaps my antiquity is an advantage after all - brought up in the less luxurious 70s, I was thoroughly refreshed by my bracing cold shower
