How much mono backing do I use before filling my reels with fireline for trolling?



I put 100 feet of mono backing and then a full spool of 300 yards of FireLine on top of that. The mono backing is simply there to stop the FireLine from spinning on the reel’s spool. 300 yards of FireLine may seem like a lot, but consider that sometimes I want to put out 300 feet of line to the lure, attach a board and then let out another 150 feet. Plus since FireLine is so durable, I can leave it on my reel a long time – so with the extra line, it is still useful even if I break off quite a few times. 10-4 FireLine is perfect for walleyes – the mono backing can be anything – I do use 10XT.
