A long trace of at least 5m I have found the best.
It pays to use quality swivels to avoid line twist as well a slender bait that doesn't act as a propeller.
Self-hooking recurve hooks like the Mustad Demon work really well with the long trace as sometimes you don't feel the bite.
If you are getting a lot of weed on your line it pays to shift to another spot. You may only need to shift a few metres to the edge of the current line.
I have had reports of fish up to 6kg being caught during recent weeks.
