That's interesting. I have heard the SCS grinds well but there is much debate among SC vs SCS fans. Does the SCS really eliminate the BB pellets from the center of flowers? With my SC I would still get small BB sized lumps in my grind that I would shake out with a quarter and cut up to get a finder grind.
I have all SC grinders, and a couple of SCS.
They are my choice... and I only use 2 piece grinders.
I have been a heavy and regular user since 1967.
I have been grinding all day every day since about 1990.
I do not understand what you mean by the BB pellets.
I have never witnessed a bb sized lump.
I fill grinder, and position it as a tire rolling on ground, and I grind back and forth a number of times.
If grinder is held flat, the meds can not use gravity, and sit still as you turn... could this be causing you a spot on grinder that is not getting your meds?
Tilt grinder and try.
2 piece always has worked fine, even though I own a collection of 4 piece.
I have used the same "cookie tin lid" as my tray... and the same card as my scraper for
15 years. There is no kief buildup on tray.. and grinder just requires a stir tool or poker to loosen up any confined vegetable matter.
I get similar grind with my Space Cases and my SCS ... but the SCS seems to turn and start the grind more easily every time.
