I have some annoying "twang" on the open D string, with La Bella DTF 760L strings.
It does not sound like fret-buzz, rather more like an extra large dose of "twang" that open strings seem to give. I pressed hard on both the nut and saddle to double-check the "witness" point. Also loosened the string, in case anything was twisted. No joy.
I usually play fretted notes, so I really only hear it when tuning. Don't think my prior Ernie Ball rounds did that, so maybe a bad string, or I twisted it beyond repair when installing.
Still...
