So, the Japanese system of numbering lines does not correlate to the line diameter? And as far as FC is concerned, are there any domestic US brands/product that make for an ideal (or slightly less than ideal) leader? I read that the big issue is the stiffness of the line is the issue, where the stiffer line is preferred (which is confusing to me, because furled lines are praised for their suppleness).
