The new 48 mm whorls for the AA #0 flier are dialed in for singles in the range of 5,600 to 34,000 ypp.
So, I brought the darkroom timer downstairs, and did some time trails.
Bottom line, spinning with DRS allows me to spin about 4 or 5 times faster than using a single drive. (Either bobbin lead or flyer lead. DRS is more than twice as fast as as conventional DD.)
The second finding was that graphite impregnated Delrin, is lower friction (faster), but the leathers made by Alden Amos run 90% as fast as the black Delrin, but much quieter.
