Howdy,

Something I saw on the back side of the package of this Berkley Forward braid caught my attention: "Conventional Braids flatten out the more they are fished."

It's the first I've ever heard a claim like that. Has anyone experienced something like that?

I pretty much use braid on my reel until I run out of line for a long cast. And I haven't had any issues yet with anything supposedly flattening out. And if it does happen, does it make any noticeable difference?

Over an extended period of time, PE can compress an ovalize. Generally, PE lines with higher number carriers, 8, 9, 16, resist flattening more so than 4 or 5 carriers.

Although they will compress, todays PE and super lines have drastically improved since the late 90s and early 2ks. The original Fireline used to flatten like a tiny ribbon, which made the...

knots weaker

casting range shorten

drastically increased drag in water (and air) at certain angles

stacked uneven on the spool, forming gaps which would become a nightmare in the dark.

Yeah I tried Fireline once and didn't like it straight out of the box.
