Just to reconfirm, a single wind creates more torque because the arm has a larger gauge of wire used to make it. The larger the gauge the more current it draws, in turn the more current, which results more magnetic field being generated in the armature. The higher winds ( double, triple, quint and even hex) use more wires of much smaller guage and in turn create less magnetic field. That's why they are smother. Just ask someone who races onroad what they run. In onroad it is all traction so they can use all the torque and more of a single.
Don't sweat the petty things...........Pet the sweaty things!!
