I have a video on making furled leaders. I also have the plans for a board in photo bucket as well as a photo tutorial on making shorb loops. I'll get a pm off to you tomorrow.
Thread leaders can be treated with any floatant to keep them from sinking, so can mono leaders!!
P.S. You have a good thing going with your Fish-In. I'll be headed up to the Michigan Fish-In that day or I would be there!
