I've gotten word from Teknomotor and they're telling me that constant torque is the way to go.
Next question is about a line reactor. Tekno is telling me that it's important to have one but I know a lot of guys are running without one. A reactor is $100 - is it absolutely necessary or not so much?
I'm a hobbyist at this so the machine won't be running 24/7, probably just several times a week for a few hours at a time.
