This sounds like an issue with the way you release the ball, not how it's drilled. You can take the most aggressive ball on the market and use the most aggressive layout, and if you throw it straight it will go straight.
It sounds like he used a variation of a full roller layout, and these typically don't produce any major change of direction. Try working on your release before spending $200 on another ball. When you release the ball, it should look like you're going to shake hands. Your hand should be behind the ball until you are about to release it, then it should rotate around the side as you release it.
Once you get comfortable, you should see your track staying more to the left of your grip, and more of a change in direction with the ball. Then you can go for a different layout that will compliment the new release better.
