XTCB-8 has all of the same great features as XTCB and more. By using 8 strands of fiber during the braiding process, P-Line has made a braid which is extremely tight and compact. The benefit to the angler is an ultra smooth finish and the ability to retain its round shape while having a smaller diameter. Add the benefits of DuPonts Teflon Surface Protector, awesome abrasion resistance, great knot strength and reduced friction, and you have the best braided Superline available to the angling community.
