Does anybody here use a mono backing to fill the spool up some (like you would do with braid) with flourocarbon? Or do you just fill the spool up with fuorocarbon? Does filling it completely with fluoro cause any kind of issues (backlashing, knotting up, and other fun things such as that?) I have been using seaquar and had no problems. Then i filled a reel up with it and it gave me a fit, however, i think i got that issue pretty well taken care of. Then i purchased sufix castable fuorocarbon 14# test and it has been nothing but a nightmare. Need some opinions on what everyone else does. Thanks
