Nice instruction and well designed set-up. I've never done much with braided line, but recently, I've figured out how to twist mono. It's different than the other vids I've seen where you have to "free hand" manage the running line ends ...I couldn't do that (sort of because it's hard to free up either hand)...my attempts would get all twisted up...find each other, etc. Braid is different than mono...once you twist mono and remove the torque, it relaxes twisted. The other change I've made is I don't like a loop connection to tippet so my end section is single strand. I also cut the last double stranded butt section and twist that together to minimize midsection knots. Mine are only three sections...single, double, and quadruple captured with a Kreh Leader knot. I can make them to almost any length since I'm not limited to the length of a jig. I tried my way once with braid...it didn't work very well, again, because braid doesn't form a "natural" amount of twists like mono, at least when done by hand. Not the greatest instruction vid, and I'm doing something quite a bit simpler, so I hope it's worth sharing.
