Sorry, didn't mean to be down on you. I know plenty of folk working to scratch up funds and interest for other areas and trails but once it get above a certain level it just all seems to go to the tweed valley. The DMBinS folk do a good job but they are fighting government inertia and habit. The morons who voted to deprive us of EU funds didn't help either.
If you head north from the tweed valley stop at Dunkeld, then head to Pitlochry and then up to Contin/Golspie area. From there head west to Torridon and down to Laggan via Fort William. That is easily 2 weeks of fun just doing the classics before you even venture into the mountains for some out there serious stuff or scoot over to Braemar/Ballater area.
