The FF Drainer Disc is the first of its kind to be seen on the Flytying market, its made out of brass and comes in many colors.. The idear was to make a Disc/Conehead that allows water to slip through the head to make more movement and some Sonic vibrations, but in the same time, push the water away from the fly to make even more movement in the materials like our FF Ufo Disc… In the 8mm version you can also feel when lifting it out of the water it slips the water easier. There are many possibilities with the FF Drainer Disc, try pull some rubberlegs out through holes, it looks crazy in the water. Comes with a holesize in 1,9mm
