This is our favorite sink tip line for Alaska. The short, heavy head loads quickly and at short range, is easy to mend, and gets down in the strike zone quickly. The density compensated tip makes strike detection easier.
Rio's MOW Tips are the ideal way to add a sink tip your switch or spey rod. Medium MOW Tips are 10 feet in length, built on a Connect Core low stretch base, feature T-11 (8 ips sink rate) in the sinking portion and come in a variety of sinking combinations. They are looped on both ends and laser labeled for easy identification.
In general Medium Tips work well on Skagit lines between 475 and 575 Grains. Pick individual tips for your needs or get the whole kit so you are covered in every situation.
