In the late 60's I used to buy salted lug from tackle shops down here in Ramsgate. Back then it was cheaper than buying fresh and was always available.
I caught my personal best plaice (4lb) from the end of Ramsgate pier using it.
Last year just before xmas I went fishing with a couple of mates. They bought so much lug (about 10 score) and were going to chuck it at the end of a blanking session. I took it home and salted it down and have been using it ever since.
It makes a good bait for flatties and I have had whiting & codling on it too.
So far this year I haven't dug or bought any fresh lug, but when I do, I am going to try it side by side to see how well it does against fresh.
