I rarely fish lures unless for bonito or freshwater, salmon etc (or did, legs to fecked` these days) Anyway, long, long time ago down Mull of Galloway direction I was bait fishing for thornback when I noticed a much older guy, probably 80 then, regularily pull out decent bass over a few days. One it turned out was 11lb. Anyway spoke to him eventually and he showed me his method. Obviously would not work on rocky bottom. He had a simple 4inch silver toby, nothing fancy just a tried and tested toby. He had various gulleys and areas where rock and sandy bits met around 30-40 yds out, from memory would be around 12ft of water. He cast the toby onto the sand and let it settle. Once settled he gave an occasional slight twitch, I imagine this disturbed the sand. Then after about 4-5 minutes he gave a sharp tug and started to wind in sink and draw, wham, time and again a bass hit. Turns out he had been a commercial rod and line fisherman and used simlar methods on his boat. He reckoned the occasional twitches sent up clouds of sand which attracted fish and then the sudden jerk and sink and draw convinced them it was some fish, hiding in the sand now trying to escape. This would be probably 1990`s but I have little doubt the method would still work just fine.
