Fishing line manufacturers produce braided lines made of Spectra fibres, which are much stronger than traditional monofilament lines. However, the Spectra material that gives these lines their strength also makes them very slippery. Consequently, it can be difficult to properly attach a braided line directly to your reel spool.
Attach a portion of monofilament line to your reel spool using an arbor knot. An arbor knot is tied by looping the line around the reel spool, tying an overhand knot with the tag end of the fishing line around the main line, and tying a second overhand knot in the tag end of the line. Monofilament line is not as slick as braided line and stretches much more than the non-stretch braided line materials. These qualities will keep the monofilament line from slipping on your reel spool while you are fishing.
Reel the monofilament line onto the reel spool until the entire exposed surface of the reel spool is covered with a layer of monofilament line. Use the thumb and forefinger of one hand to maintain maintaining pressure on the monofilament line while reeling it onto the spool. Trim away any excess monofilament line.
Attach your braided line to the end of the monofilament line using a uni-to-uni-splice knot. To tie this knot, overlap the last 12 inches of the braided an monofilament lines. Then, loop the monofilament line around both lines once, pass the tag end of the monofilament line through that loop four to seven times, and tighten the knot. Next, perform the same steps with the braided line. Finally, pull the main portions of the braided and monofilament lines to jam the knots together.
Reel the braided line onto the reel spool until the spool is full. Check your reel owner's manual to determine just how much line the reel can hold. Use the thumb and forefinger of one hand to maintain maintaining pressure on the braided line while reeling it onto the spool. Trim away any excess braided line once the reel spool is full and ready for fishing.
When determining the line capacity of the reel spool, the pertinent line characteristic you should rely on is line diameter rather than the pound test strength of the line. Braided lines are much stronger than monofilament lines of the same diameter, but the reel has same line capacity for monofilament or braided lines if the lines are of the same diameter.
Don't try to cut braided lines with nail clippers or the "nippers" that many anglers use to cut monofilament lines. Due to their strength and toughness, most braided lines cannot be cut with anything less than a pair of sharp scissors.
