Sure! When we're first learning to heel toe, its often very abrupt and bucky when the transmission is reengaged since you have to spin up all those driveline components; to really do it right you have to get your rpms into a 200-300 rpm window of where you are matching speed. With lighter driveline components the practical effect is the window for a smooth feeling downshift now widens to about 500-600 RPM. It's not a crazy difference but its very noticeable on the track at higher speeds. Even my HPDE instructor could tell it was there after a lap in the car haha
