My practice line for my baitcaster, but my problem is that i need to spool some more on. I don't know how to do this. My first spool of line was spooled by Gander Mountain.

Tie line to reel spool, secure filler spool, crank till line level is 1/8-1/4" from edge of reel spool.  Maintain tension on line.

You can find specific knot for flurocarbon spooling, and it's hard for me to always respool. Maybe someone can help with this....more

I'm not entirely sure that was English, but i think you asked for help with a knot?
