Marks on Achill island

[bigman25]

Howyiz lads this is me first post on the site and any help would be much appreciated. Am headin down to achill the weekend and dont really have a clue on where abouts to fish or the best baits to use. Does anyone reckon would it be worth getting some rag in dublin before i head down? Oh and is there any marks for mackerel down there for a bit of bait or should i bring some too?? Thanks
