thanks everyone for all your comments
PeteR - don't think you'd have any problems given the length of your last walk !
jonny, Johnny, GillC - probably a good idea going in the snow - fewer people I'd guess
Collaciotach - couldn't agree more - not sure I'd want to go up Ben Nevis again after that
pigeon - sorry couldn't see you - didn't have my glasses with me
gammy, dave - only way I can manage is to leave early, get back late and just plod on
JohnJoe - it's not as hard a as you think; once you're up there the height drops aren't too bad
jimandandrea, Chris, fudgie, Bod - it's great when you get the weather and the views !
