Hmmm,
depends on if are already in playing fingertip drilling or conventional grip. If the second is the case, stay with a polyester ball to practice your approach and consitency. It's the basics to step up to hook a ball.
If you are starting to play fingertip, have a trustworthy pro or coach give you advice. In my case I was lucky when I wanted to start with a "better" ball, because I met a very good pro. I got a Brunswick Power Groove Plum Pearl drilled for my hand, but I kept my polyester ball for spares.
I think the Power Grooves are a good beginner's choice, because their shell gives enough hook on medium to dry conditions. And they are not too expensive to start release experiments with...
Do NOT make the mistake to buy a high performance ball, even a used one (EVEN WORSE!). It is important to have a sound technique to build up upon, not the glitz of a fancy ball which might not fit your style or lane conditions. Training and consistency is important. I suppose that after some time, you will step up to lower RG balls and stronger shells. It comes natural, do not hurry.
You can keep your polyester ball, maybe think about re-drilling it for fingertip when you feel comfortable with this release, to keep it as a spare ball especially for corner pins. Should make a sound combo.
But starting out with a polyester ball in the first place should be the best choice.
Hope this helps a bit?
