Dazza I will be up there working and fishing again next week, so will let you know the score with regards to 'if its fishing or not'. Know a 'few' marks up there which have been sucessfull so far this season and in the past, but it will just depend on the conditions; coz by the end of next week when you are planning to go Windguru is predicting 15 - 20 mph ENE winds mate.
From what I have read elsewhere I think a few lads are travelling up there from our neck of the woods this weekend for a sesh too. Good place to check is the Scotland section on World Sea Fishing site for info.
As far as bait goes mate its the same as we would use round our neck of the woods (razor/mussel/squid/runnydown/crab/lug/rag etc) but dont be frightened to fish a rod with a big mackerel bait because fish bait really does seem to sort out the better fish and the local lads seem to swear by it. All the best mate and I will try and remember to drop you a line next week.
