i use a carp rod mate, anything from 10ft over.
i prefer 12ft carp rod, its can cast weights under 1oz up to around 3ozs
2 hook flapper, small hooks size2 down over.
rag and a small strip of makerel
small lob around 30yds, you want the lead to be rolling a wee bit, not too much in the tide.
every few mins, just reel in a wee bit or drag the lead towards you to give the bait some attraction. you will feel the flatties rattle the rod. i tend not to strike on the first few rattles as they normally nipp the makerel and worm tail before they take the hook.
i use a light spinning reel / carp reel with 15lb line.
just keep changing your leads to follow the tide run.
big bags of flatties
thats all im going to tell you
