Reattaching a supply line

[arbor1]

Love the forum and the great advice here. So, here goes: Does it harm the longevity of a new toilet supply line if it is removed and then attached again? I'm dissatisfied with the performance of a Fluidmaster repair kit I installed a few weeks and want to replace with a Korky. Do I need to replace the supply line again?

If it was new a few weeks ago, I'd leave it. Otherwise, replace it.
