Following the clues i think i've got it (leven strain troots and River Meig final giveaway)
So (and Mike could actually claim it) i'm going for Beannacharain, but better known as Scardroy (named after the local lodge)
Had a season ticket for this area years back (Achonachie Angling Club) but never explored area near enough. Need to put that right soon, and River Meig needs some serious attention. Loch Meig, however, was a water i was never so keen on for some reason.

PS i'll post another offering later if no-one's beaten me to it (and assuming i've got the right water)
