dont want to tell you how to suck eggs but next time you get bites like that dont leave any worm hanging loose. keep all the worm on the hook.i was there just for an hour on my way home from llandwyn on 12th.
fished on high water from the jetty. had three stonking one hit bites on successive casts on lug worm to a 2/0 hook.
then the tide really started and we went home.
didnt connect with anything but the bites took the worm each time just up to the hook.
