The unique weight forward design swims perfectly in the water. The steeper forward taper pushes the wing materials into position perfectly. Available in brass only. 13mm in length, .88 grams per tube.
The Skittle tube is the one with the best balance among all the heavy tubes. It has enough weight at the front end to push the fly down and hold it firmly in strong currents. The rear part is thin an allows the rear end of the fly to ride level.
