Nylon monofilament fishing line can be good value for money. This one comes in spools of 100m or 500m and it is clear and strong. It has abrasion resistance and knot strength making it really suitable for fishing. It has low stretch as well and extra sensitivity due to its constant and uniform diameter. It has a high-density construction which means that it will sink faster and is not absorbent. It is thin and lightweight and so it should work really well. It also has excellent transparency which means that it is barely visible to fish.
