The challenge that I found with the S16 was to learn to put my foot all the way down,
instead of gradually speeding up like we tend to do on a DSM.
Can't answer re the Pfaff, but am pretty sure they would follow the S16 standards.
FYI ... when I was shopping, I called HQ helpline and asked questions about the Babylock version.
They had no problems helping to educate me, being that they built both machines.
So you may want to give them a call.
