Re-adjust your sense of humour slightly, so long as you can enjoy an hour or two humphing through trackless bog in the rain*, you will enjoy yourself anywhere in scotland, just pick an area, buy the map and choose your route. You sound better equipped for it than I am yet I’ve managed quite a few 2/3/4/14 dayers and made it back in one piece!
I posted a couple of stories about my first forays into remote scottish stuff on my blog ianezzi.blogspot.com and if you click my user name and check the ‘threads started’ section, there’s a few more stories.
*this is of course the very worst case scenario, there is also miles of beautiful trail and the sun occasionally shines!
