I have a sprung brass button clutch (might be what you meant by cushioned).
Different engines will differ though.. e.g. when I had this clutch behind the RB20, I needed to give it ~3000rpm and drop the clutch to take off without stalling. Now with the RB30 (heaps of low down torque), I blip the throttle as I'm taking up the slack in the pedal, then quickly past the friction point as the revs start to drop and back on the gas as the car starts to move.
You'll adapt in time, just don't ride it
