Braid is the line that changes how fishing feels. It has almost no stretch, so you feel a bluegill peck on a jig 40 feet away, and it is far thinner than monofilament of the same strength, so a small spinning reel holds more of it and it cuts through grass. It also floats, shows up in clear water, slips on a bare spool and cuts your finger if you try to snap it. Every one of those has a fix, and most of them are cheap.
Our fishing line guide already settles braid versus mono versus fluorocarbon and ranks one braid. This page is for the angler who has decided on braid and now faces a wall of near-identical spools. It ranks nine, says which strength and colour each link actually opens, and puts a number on a question most braid lists skip: what pound test of braid to spool. Braid listings are a menu of strengths and lengths, so the size we name is a sensible starting point, not the only one sold.
If you only buy one, get Sufix 832 in 10 to 15 lb for a spinning reel, add a fluorocarbon leader, and put a little mono backing under it. Tom has not tested these lines. The ratings and review counts are Amazon buyers', read off each listing while this page was built, and Amazon shares one rating across every size of a line.
