Hard luck chris ,good to see someone trying these spots, never tried skerries for beach fishing ,tried spinning that beach once got a small seatrout, years ago ,but if there's small ones there's big ones, I'd love to try shennick island spit on the fill but don't fancy being stuck there for hours over high tide, bass in north dublin can turn up anywhere,but if there's trout and flounder on that beach shud be bass, I think rasor is a good bait anywhere the trawlers dredge ,its what they are used to eating from all the discard s in the water, I wouldn't worry about lug never seems to work for me, around the area but does elsewhere,anyway keep plugging away, this is the time for the big bass, good luck happy fishing
