DescriptionESP Syncro XT Loaded Line The XT of Syncro literally stands for extra tough, indicating that this exceptional monofilament is highly abrasion resistant and durable. PRODUCT INFORMATION Following its launch in 2011, the original ESP Syncro XT mono has grown to become one of the most widely used and well respected top end mainlines available. And with very good reason, it ticks all the boxes regarding what's required from a top performing carp mono: unbeatable knot strength, optimum stretch, superb abrasion resistance without being wiry and this relative suppleness makes it a front-runner when it comes to distance casting. Over the intervening period since the initial launch, we have carried on testing various different mono samples and have yet to find anything better than Syncro, which combined all the attributes required. However, during this testing process, we explored different colours having been asked by some of our sponsored anglers for a darker olive green. So Syncro XT Loaded was born and the anglers that tested it for ESP have been completely sold on it. Upon casting out it sinks through the surface film virtually unaided until it just hangs from the rod tips. And if a slack line approach is required it stays that way, lying tight to the bottom to the extent that you can feel it peeling up off the lake bed when winding in.
