Now, this doesn’t mean that just because braid is smaller in diameter than mono is that you should opt for the heaviest pound test possible.
A 20 lb test braided line is equivalent in diameter to a 6 lb test mono line. If you want to maximize for casting distance with a spinning reel, without sacrificing line strength, you really need to go with braid. That’s because braided line is so much smaller in diameter compared to monofilament. The braid vs mono debate continues! However, unless you plan on using 6 lb mono on all of your reels, braid wins this battle hands down. Use Braided Fishing Line for Maximum Distance
