I have been using 12# Sufix advance since I began trolling for walleye about 3 years ago. I have never had a line break in all that time, but I've not caught any walleye over 8 lbs. yet either. I use the 50 + 2 precision trolling method quite a bit so I don't want to go heavier than 12# so my depths will be more accurate. I have a couple rods with 20# braid but I've only used them for jigging with a 6 ft. fluorocarbon leader. I am also told that if you use dipsies that you will want at least 20# or heavier braid but I have no experience with dipsies yet. The Sufix advance is a bit less stretchy than regular mono which I like when I want to release a board when I get a fish on. Hope this is helpful
