Where are the black lug?!

I know most people wish to keep their favourite bait diggin spots secret, But I've been havin problems getttin decent lug lately, I tend to dig out near sutton, but really only gettin blow lug..
I used to dig up near wooden bridge, but ain;t in a while... If you know any decent spots near these spots/malahide/baldoyle/clontarf etc... I'd appreciate a PM, I'd keep it secret.. cheers..
