Galaxie Bowling

I've recently been getting a lot more into bowling. My highest score is a 245 which I just got tonight, and I can get between 155-180 consistently. However, my bowling style is...rather unconventional. I don't bowl with three fingers, I bowl with two. I put a massive spin on the ball and most of the time, I can get it to hook right into the pocket--but that all depends on the ball. At the alley where I bowl, there is a "Galaxie 300" ball, which I recently found out has been discontinued; quite awhile ago, in fact. But the ball works for me, and almost nobody uses it. Ever. Of course, the alley wouldn't let me take it.

So you see, I have a bit of a problem here. I'm afraid that if I buy a ball with a hook on it, it'll hook WAY too much and I'll have wasted my money on a ball I can't use. I need a bowling ball that does well on medium-heavy oil lanes, with a nice bit of hook, but not so much it sweeps right past the pins.

Any help would be greatly appreciated.
