The red color makes it easier to identify a set of rigs in your tackle box. However, this doesn’t mean you can skip adjusting the line diameter to match the bait and the current: a thicker line holds its shape better, but at the cost of a less natural presentation.
To minimize tangles, also adjust the length of the main line to match the spacing between the branch lines. The 100-meter spool provides enough line to replace any damaged sections. Inspect the areas near the knots and hooks before reusing a rig.
