Platypus Lo-Stretch is a monofilament line that has the low stretch of a braid! The advantage of braid is the incredible sensitivity you get from near zero stretch. Platypus Lo-Stretch has the lowest stretch possible from a monofilament. Much has been written about the advantages of braid, but monofilament has its place in fishing as well. Some stretch in your fishing line can be good. Braid has almost no stretch, which makes the line incredibly sensitive, but can sometimes result in pulled hooks and lost fish. Platypus Lo-Stretch gives you the best of both worlds - enough stretch to provide a slight shock absorbing quality, with minimum stretch for maximum sensitivity! All braided lines have weaker knot strength than monofilament, and knots for braids typically require more turns and wraps than regular knots. Good knots tied with Platypus Lo-Stretch give 100% knot strength, whereas excellent knots tied in braid give 85% knot strength.
