OK...I'm going to clarify.....
We use 'top' clip...that's the longest we can get, and that is 5 to 7 inch wool fibers. Wool is not a continuous fiber.
Once you cut off the rubber, you now have cut thousands of fibers(individual strands)...and some are not connected underneath the string, but they were connected in the rubber glue you just cut off......
So, there are a bunch of individual fibers just 'floating' in the twist of each end of yarn. When you shoot the bow, those loose ends start to fly out, some are longer than others an they hang on a bit longer.
After a dozen or so shots, the large majority of those floaters should be gone.
If you think those Hush Puppies shed, you should see our wool cut pile carpets shed. Makes great dubbing for fly tying.
