For years, we've been building our own loops into sink tips via whipped loops, allowing us to hit trout and steelhead streams with sink tips of many different weights and lengths. Typically, we use different colored thread to help distinguish tips of different weights. The loops are relatively easy to build and when reinforced with UV knot sense are actually quite strong. While these loops have generally worked well, they often don't turn out as nice and neat as we'd like, and the thread wraps take a beating over time and have failed on us on more than one occasion. The alternative to whipped loops is welded loops which, while many anglers think can only be created by the manufacturer at the factory, can actually be made very easily at home.
A new video by RIO highlights the process and, with RIO's recent addition of colored (by weight) InTouch Level T sink tip material, has us a bit giddy about the idea of revamping our sink tip arsenal with vast array of color-coded tips in varying lengths with neat, manufacturer-quality welded loops.
