Because I use the chamberlain releases on my downriggers (I don't like putting a twist in mono - had a couple of break offs) I generally use 10-12# powerpro braid with 10 feet or so of 8 - 10# fluorocarbon leader. I use ultra light, slow action fiberglass rods, so I have plenty of cushion to make up for the lack of stretch in the line, and my catch hook/rate is generally pretty good (I'm 10/11 and 12/13 this year, but I've had some 50/50 days in the past).
