Whats the best 10# fluorocarbon line for $15 or less?

Fluoro changes in price with # test. That being said, seaguar red label is probably the best cheaper fluoro.

I think Sunline Sniper FC is aso a cheaper FC and a darn good one too for not much more than a Big Mac combo at Mickey D's.

I agree with John G....Sunline FC Sniper hands down! Spend the extra $5.00 for a good Fluorocarbon....$19.99 for 10# - 200 yards

May not be the answer you're looking for but imho line is not one of the places to try to be cheap. Kinda holds what you want on the other end.

I have some Red Label 6# test that is super easy to manage but good grief, the stretch is crazy!
