And seriously, MR 300, with the way you bowl, the ball probably won't be much different than any of your high end oilers. With your direct lines, slower ball speed, and low revs, balls will blend together in terms of reaction shape, oil handling, and so forth. Which leaves me questioning why you have numerous balls which are very similar in the first place...
But really, If i were you, I'd save the money, take care of my current equipment, and get a coach.
