I spooled my pike jigging rod with 50# Fireline. Partly because I had some laying around, but also because it doesn't hold much water (like braid), very abrasion resistant (for ice hole contact) and is thick enough to handle well if I have to resort to handlining. I treat the first 50' or so with a silicone fly line dressing to reduce water pickup even more. There's 20# uncoated steel or 60# fluoro for leader.........
