Min and capitalize on the freer flowing Syn or cost cutting Min...
Dream on.
If metal was perfectly smooth then maybe that theory would hold water however since no metal moving parts are perfectly smooth this idea doesn't fly.
In fact varying sized molecules are better because they fill the irregularities thus creating a better wedge.
You need to get away from believing the marketing department. It scares me that you've got a shop and people might actually listen to you.
Luckily here that's not a problem.
