The extra fast whorl is indeed very fast
"I wanted to try out some more whorl ratios with my new (to me at least) Fantasia, so I started off with the "extra fast" whorl, and I'm not sure what I expected, but it is indeed incredibly fast. Great for fine to super fine yarns and slippery fibers like silk. Honestly it's a bit too fast, so now I'm ordering the "fast" whorl. They. work great, and there's a small screw on the side that can be loosened or tightened as needed"
