Sorry I'm a little fuzzy. Did an early morning trip down the Canal to see if the chums were in-- the scouts are, but visibility (because of the floods) was about three inches-- that's a weird condition for saltwater.
Anyway-- I use a single uni knot (tied with 30-pound leader material) on the end of the fly line. If I'm after big fish, I tie a small overhand knot in the fly line and hit the joint with CA glue. I haven't had this fail yet, but I suppose at some point it will.
I tried to find you at the end of the show for a catch up, but you weren't in the booth the two times I walked by... I hope you had a good show. I know CND got exposure-- on the shuttle ride to the airport, three people were talking about the rods.
