Competition Spinning

If one wants to spin very fast,  one needs fiber that has been oiled, combed, and drawn through a very fine diz.  You are not going to get that in a spinning competition because competitions are organized for woolen spinners. As such the fiber will be roving or batts.

Yes, DRS will allow one to spin as fast as is possible with supplied fiber, but one is not able to take full advantage of the DRS technology without the appropriately prepared fiber.  Contrary to popular belief, spinning worsted with DRS is the fastest spinning possible.
