"Brushless provides a healthy level of torque and ability to move stuff."

For drums or objects with low moments of inertia yes but for larger discs with high moments of inertia the raw torque generated by a brushed motor can't be matched with brushless.

With brushed you generally pay a lot for the motor and can use a relatively cheap solenoid to give you on off control. Brushless tends to have cheaper motors but the control works out to be the expensive part.

Right now I just don't see brushless having the reliability in the arena when compared to a brushed spinner set up.
