I use 30# PP Hi Vis and 6# Fluoro Leader. I wrap 7-9 times down and 7-9 times back and have had no breaks at the knot.
Flukes are notorious for twist, so I also use a light swivel up the line.

Isn't it Otters that make such a mess on the docks in the Winter time? I keep a Pontoon at Long Creek and they
leave crap (literally) all over the dock.
