The AirFlo Skagit II Compact Head is the most popular 2-handed line in America, and for good reason.  These short, looped floating Compact Heads should be married to a shooting line and capped with a tungsten sinking tip appropriate for the situation and the rod.

Skagit Compact Heads are available in 30 grain increments, beginning with 360 grains (for a 4/5 rod) and increasing to 720 grains (10 weight).  These lines easily toss heavily weighted flies connected to a short leader and attach to the end of 5' to 15' of tungsten.
