RIO’s iMOW tips have an intermediate section, instead of a floating, which creates a smooth depth transition between a floating body and fast sinking tip, and perfect contact between the angler and the fly, they are also the ideal tip for intermediate based Skagit heads, like RIO’s iFlight. There are three weight series (Light, Medium and Heavy) and four tips within each series, as well as a complete kit with all 4 tips of a series packaged in a RIO leader wallet.
Light iMOW Tips feature T-8 for a sinking section (with a sink rate of about 7” per second) and are most suitable for Skagit lines of 475 grains and less.
Medium iMOW Tips feature T-11 for a sinking section (with a sink rate of about 8” per second) and are most suitable for Skagit lines between 475 and 575 grains.
Heavy iMOW Tips feature T-14 for a sinking section (with a sink rate of about 9” per second) and are most suitable for Skagit heads of 575 grains and heavier.
