I frequently do the no throttle start in my ECO MT. You can do both, but it takes a little bit of practice to do a smooth clutch out/throttle down start. The friction point in my son's LS MT is just shy of half way up the pedal travel. Does the car start moving as soon as the clutch is coming off the floor? If so it should be checked to ensure there are no problems with the hydraulics that control the clutch.
