Poly changes characteristics after time. This is not an opinion, its a fact published in numerous papers. Specifically, it becomes less elastic and more stiff over time. Ie, it feels "board like". Each poly takes a different amount of time.
You may still be able to "play" with dead poly, and it might not bother you. For those that have arm issues and/or want the originally playability, you MUST cut it out when it goes dead.
Poly is cheap in reels. If you are buying poly because it "lasts a ling time" you are fooling yourself, unless you want to play with dead poly.
As you progress in swing speed it eventually becomes a moot point as you'll snap it as it goes dead, assuming you are matching your gauge correctly.
