For the main feeder fishing line, choose the thinnest diameter that covers the cast load, bottom conditions and expected pull-out effort. Don't go down to a finer version just for the distance. Rough bottom or sharp edges require more frequent checks on the first meters and a reasonable stock of strength.
The coil should lie evenly and without overfilling the spool. Make the knot carefully, moisten it according to the type used and cut off the end only after final tightening. The feeder gum is a separate elastic element of the rig, not a variant of the knit line; use it only when the specific arrangement requires it. After the first load, check that the fishing line has not cut into the lower layers.
In a river, the current puts pressure on the line, so the diameter and position of the tip have a direct meaning. On a dam or canal, distance and relief can be leading. After each change of feeder, check that the load remains within the limits of both the fishing line and the chosen fishing line.
Before casting, stretch a few meters and look for a unravelling, flattening or rubbing. If the damage is near the working end, remove the affected area and tie the rig again. Keep the bigeer roll and spool clean, because the build-up at these points can damage the line and create uneven winding. Keep the spare coil closed and away from sharp accessories.
Before you finish the feeder line, open fishing lines and leaders for feeder fishing and check how the leader fits into the intended rig. Then use Fishing accessories for a look at the other accessories, and Knitted fishing lines for comparison with decisions considered in other fishing approaches.
