I assert that spinning worsted singles can be divided into drafting and inserting twist. I assert that the wool most naturally and easily assembles into bundles of about 20 fibers. A single of 20 staples is the spin count of the wool. At 20 staples a 70 count will spin to 70 hanks per pound and a 40 count wool will spin to 40 hanks per pound.
Thus, if you need 30,000 ypp singles, I think it is easier to spin them from 54 count wool than from a 70 count wool such as Merino. I think that it is easier to spin 22,400 ypp singles from 40 count wool than from 50 or 70 count wools such as Suffolk or Merino.
Using either the right spin count wool or the finer wool, the required twist is the same. The only thing different is the drafting effort. And, I think that a smooth, uniform single is more easily drafted when the spin count of the wool matches the spin count of the desired single.
This goes directly against the current conventional wisdom. However, mostly that wisdom is recited by folks without much experience in spinning various wools at their spin count.
