I purchased a Nor bobbin at last years' Great Waters expo. Less than a week later, I spotted Faruk's bobbin in Fly Tyer magazine. I was pretty annoyed about having to respool the thread on the Nor bobbin, and immediately ordered the Ekich. Once I started using the Ekich, I never went back. Change the thread? No problem, just pop on a different spool. Done with the tie? No problem, just release the spool at the length wanted. (The Nor Bobbin requires the thread to be pulled past the next catch point, sometimes leaving about 1 foot of thread hanging around for the next fly.) Retaining thread quality? Make sense to me. I just really like the Ekich. Great product, and wish I had thought of it first. My Nor bobbin was sold on eBay last summer.
