Let us begin by introducing the most popular and widely used category of line; monofilament. Monofilament lines are made from a mixture of polymers. It was heated in high temperature until it forms a liquid and then molded to fold strands of line. The final product is put into spools. Qualities such as strength and color can be modified during this production process. The most important factor of monofilament lines is that it stretches. Depending on what setup you want to configure, the stretch factor can be either beneficial or it could become a setback. When choosing monofilament, keep in mind that the more expensive lines usually went through more quality control and will provide better performance.
