Conical burrs have a slower rpm, so less heat during grind.
They also have a wider grinding area to disperse heat.
A Honkie barista recently claimed that heat is better though, but many are doubtful in the claim.
E61 has a lot of makers, ECM, Bezzera, VBM, Expobar, etc. I think more than 10 companies copying it. If it's not good, i think won't have 10 over established companies copying? Maybe because it's an open patent?
From what i been reading, PID adjust the boiler temperature so will inevitably affect the HX temperature. The fluctuation is also lesser. Got abnormalities, I think u can see it better. You may have more confidence is seeing exact number that guesstimate.
I'll pick BB005 or Q50E.
Hope the info helps.
Thank you very much for your input
