Also, the longer the distance from the fulcrum, the less pressure needed to produce the same torque.

Well, I agree with most of that with some small quibbles.
Resistance to fade depends mostly on the choice of pads. Better ducting can help some, and better rotor design can help a little.
Heavier rotors absorb more heat, and fancy rotor designs can dissipate heat faster, but bigger rotor diameter and width by themselves have no effect on heat.
