The Rocket Ship for me is easily 6 more than my IQ Tour. With the added Diff, you're getting more flare and more potential. Mine has stayed in the bag lately because the lane conditions have played drier and once I get deeper in and start targeting inside of 3rd, I can't get the ball to slow down enough to kick the corner out. Overall I'm extremely impressed. However, I feel like this will be one of those balls that are underrated so it'll go by the waste side. Overall to me, this one is the best of the 3 in the Rocket line. The most versatile and usable solid outside of the IQ Tour.
