I've only done Kingsmuir/Oban once, late December, it was clear all the way there, but on the way back about 50% cloud close to the summits. Stayed above it still in sight of the surface & worried in case it clagged in all over. It didn't & decended from 4/5000ft in the flatlands south of Perth.
I think I found your strip on Saturday east of Forfar, couldn't see any activity on the ground so went home. Nice looking strip, & looks wide enough for my suboptimal landings.
