Im pretty dead set that I want to get a rocket ship. It seems like it's the perfect benchmark ball with a great reaction to start with. What other balls would you build around it for an arsenal? Higher or lower in both storm and roto grip line. I like the hywire, hustles, wreck it, snap lock. Not sure how any of those would fit. I currently have a wrecker but it's getting old so I will probably push that out of the bag with new stuff. Just wondering on ball ups and ball downs although I probably won't need to ball up as it looks strong and I bowl on old wood lanes.
