Are you using mono or braid? You often see a topshot of mono to provide some stretch. Some folks also recommend a long leader that is more abrasion-resistant if they are fishing structure that will abrade the line.
It appears IGFA heavy tackle rules do not let you go with anything longer than 30':

There are plenty of guys there that fish out of your part of the coast. If you like, I can give you some names of guys that you could PM for info if you do not want to post the questions.




I can't imagine how anybody could do such a thing with thread.
