*Update*
The ball hooked a bit, maybe I need to turn my wrist more
If you try to force a low friction, low flare potential ball to hook when there is too much oil for it by over rotating the wrist, you could very well hurt yourself.
If you want to take bowling just a bit more seriously, and want to hook the shot, then YES, you need to buy a ball designed for that.
You won't have to spend a fortune though. Probably a good, mid level ball will set you back around $125-$150 drilled and ready. Catch something on sale or closeout and you might save even more.
Lots of people have bought Ebonite Cyclones and been very surprised with their performance, but ALL manufacturers have great stuff along those same lines, so you probably need to check around and shop well before making your purchase.
Good luck.
