Stren Original 14lb - 330 Yard Spool. This is the line used on the Fishing Addiction Gear Boat when trolling for walleye! .014 line diameter matches the line used on the precision trolling data app! This allows you to increase your breaking strength but still follow the dive curves. One 330 Yard spool should calibrate 3 line counter reels, if you use backer. Breaking a 330 yard spool onto 3 reels gives you 330 FT of main line.
