Hi Jack!
John,
To further explain, Betty's lines are the silky, smooth ones. My lines tend to be more abrasive, like horse hair (alternatively you may insert another equine for horse...)
I hope that explains things.
BTW, and accidently almost being on-topic, Jack, I need to buy another one of your furled thread leaders. Believe it or not, I put a wind knot in the one I had been using... <blushing>
