I'm heading up to the Cairngorms for a couple pf days at the end of June (28th & 29th), hoping to get on some of the classic rock routes there. I climb a few times a week at around HVS, and am working towards my MIA assessment. However, on my Cairngorms trip I'm really look at getting some of the Classic Rock routes ticked - ideally Eagle Ridge on Lochnagar, and maybe Squareface & Mitre Ridge, or Talisman, although that's a lot of walking for just 2 days.
I'm actually based down in the Lakes, but try to get up to Scotland a few times each year.
Let me know if you're available and interested for those two days.
