When writing a review, I generally refrain from calling the ball good or bad, I try to simply describe it's attributes and strengths. There's a saying that has gone around the industry, "There are no bad balls, just bad ball reaction." While companies don't release "bad" bowling balls, they can look bad if they don't match up to your style, or you are using them on the wrong conditions. However, there are those balls that seem to just be better than the rest for whatever reason, and I feel the Rocket Ship is one of them. I can comfortably say that I believe this is the most versatile ball currently on the market, perhaps even moreso than the legendary Hyroad. This ball will cover the widest variety of lane conditions for the widest variety of bowlers. This is always my first ball out of the bag, and always the first selection to take to tournaments. For me, this is definitely a must have ball.
