We was drifting a wreck about 16 miles south of Portland Bill.
Not sure if I use them correctly or not, I just leave the dame thing down there (bumping on the bottom) and let the fish do the work. 2 other ling was also boarded, one at about 15 and the other about 8, both spilled their guts cos they were deeply hooked, my hook was nicely on the corner of it's mouth.
What I have found out about the pouts, they prefer the beads, all the other guys were catching pouts, but my scratching trace (thanks Billy) which is full of beads and queins, works so well, as soon as it hit the bottom, within 1 minutes (mostlt within 20 seconds) I caught countless pairs using the rig.
