Powerflex® has been engineered with very low stretch, allowing more power direct to the lead during the compression stage of the cast and launching your lead to achieve vital extra yards. With Powerflex®, knots bed down exceptionally well, helping it cast smoothly and reducing weed pickup on retrieval. Powerflex® is the first choice shockleader for many of the world's best international anglers and has dominated world championship events for the past fifteen years. Powerflex® is extremely strong with a very high knot strength, making it possibly the safest, most reliable shock leader available.
