Question for you T-3000 (or commercial rod) owners. I recently upgraded to heat-treated commercial T-3000 rods and they are a huge improvement over my previous 20 year old, bent rods. I have noticed, however, that they make sounds (a sort of buzzing noise akin to running your fingernail over a ribbed surface) and aren't quite as slick as the old rods - even when lubricated.
Do either of these things change over time?
