i am a roto grip and storm fan. this ball is gettin the same level of talk about it as that nano pearl did. i bought the nano pearl and i was not that impressed with it. i like the arcs and design of the core and coverstock of the defiant and i hope it is better than the cell like some say it will be. but come on. is all this talk really necessary? when not too many people have even seen the balls real motion in person yet. all we see on video reviews, is when the ball strikes. i mean come on, i throw nearly 20-25 strikes everytime i bowl league

 

I was going to post something similar to Jesse on this one. I haven't thrown an Invasion, but everyone I saw throw it had mixed feelings about it. They liked the balls motion but found it to be inconsistent. But everyone I saw throwing it was RH as well.

 

From what I have seen on the Defiant, it would satisfy what you are looking for LL. I pick mine up tonight actually. Just in time as we start Shark tonight in my PBAX league. So once I have thrown it a few weeks, I will post a full review.

nothing like an invasion. way more predictable. more forgiving and a lot more pin reaction and a hell of a lot easier to make adjustments to. whether its carry down or burnt lanes. this ball is the best thing i have ever used.
