RE: Best Fishing Line
josh is talking about bass.
I'm pretty much a non-braid guy. I can't find anything that manage well. Power Pro is pretty good, but right now, i've got my rods rigged with differeing strengths of Berkley Trilene XT. Very abrasion resistant. The rest have Trilene Sensation, XL, or Vanish flourocarbon.
for trolling on pike, i'd use braid like Power pro or fireline. Probably 20 lb should do it.
