Selon les premiers avis, la lenteur n'est pas forcément un défaut :
So, Impulse is pretty great. Like I mentioned after checking out on-ride videos, Impulse has lots of little G-force "kicks" throughout the layout that make it really interesting and fun. The inversions are all really unusual, too. They kind of take the time to make you aware that you're upside down for a second or so before dragging you into the next element. The heartline roll gives you great hang time, and the spiral immediately afterward is pretty forceful. I was actually fairly dizzy for a few seconds upon hitting the final brake run!
