Choose the Max Spider Nylon for its nylon leader section, whose diameter can be adjusted to suit the fly and the target fish. Consider the specified strength in relation to the available space for fighting a fish: a crowded area requires more slack than an open spot. Take care when tying the knot, as the strength of the connection contributes to the overall strength of the rig. The 100-meter spool is suitable for successive tip replacements. Be sure to check its 6.3-centimeter outer diameter before mounting it on a spool holder.
