I've read many times that bigger grinders are more consistent and more stable than smaller ones.
Why are big titan grinders (esp. big conicals) more consistent and why is a certain grind setting more stable with these grinders compared to the smaller ones?
I've to adjust my Vario almost everyday and some times from session to session. With the Bezzera 48 mm conical only every couple of days. So I can imagine that real big conicals (>68 mm) are even more stable?
So I'm getting really interested in the Pharos hand grinder
Are the big conicals the best in this regard or are big flat burr grinders (>65 mm) equally stable?
Has it something to do with conical vs flat? Or grind surface? Or shape and profile of the burrs?
