Lot of the tour guys run 8oz snaps and apparently it’s a 1:1 ratio for line out and feet down I have 8oz snaps but have never tested the method. I’ve tried all the fancy precision trolling BS the 50/50 method or the +1 method but I’ll be honest 20–30ft lead and a 3-4oz snap let it hit bottom reel it up a few turns and you’ll fill the live well up in van hook .
