I have a week down in Padstein coming up, and will be targetting the Mullet both in the harbour and on the outer harbour wall I usually use a size 10,or 8, to 7 lb flouro, 8 lb mono main line, and have found them to be just about right for breadflake .
I fish two methods , either a flowing trace above a sinker downtide of a weighted onion sack hung down the harbour wall, mashed bread in the sack, and breadflake on the hook, or a plain freshwater waggler float above a similar set up as above, the Mullet dont seem put off at all by the 7 lb flouro. I usually use a heavy quivertip rod for the breadflake downtide of the onion sack, and a heavy float rod for the waggler setup.I have seen some mahoosive mullet there in the past, and would not want to be undergunned in the rod/ line dept.
Seeing as the weather forecast is not so good I will probably be after the Mullet in the relative shelter of the harbour as opposed to getting soaked and blown inside out on the beaches or rock marks.
