LOL I dont even think that flourocarbon was available during the steenie heyday when the population was collapsed, so no it is not a must, never used it myself for that?!..Guys used to go out at plett at night with skiboats and just freegaff the jumbo adults, there were so many tailing behind the backlines decades ago..or at least those are the stories that I have heard.
I use a hook snood of 0.6mmto 0.7mm for them, others might disagree..I prefer longer snood and stiffer line hence 0.7mm.
