When you buy a new ball, it comes with a drill sheet. The drill sheet gives recommended layouts for high, low, and medium trackers.
However, it all depends on what type of reaction you want from the piece of equipment you have drilled, as to how you should lay it out.
Did your driller measure your PAP? This is the recommended way to find good layouts for each new piece of equipment.
That being said, there is no magical lay out that is going to all of a sudden turn you into a 230 average bowler. If you're really looking to get higher scores and become a better play, I would suggest coaching.
Best of luck to you and Happy Holidays!
EDIT: In your profile it says you are a stroker. I am a lefty stroker, and what I have found is the smoother the equipment the better. My favorite type of layout for my game is stacking up the pin and cg, while placing the mass bias on the negative side of the thumb. I drilled up a Black Widow this way, and while it's still plenty agressive, it is super smooth.
It would all depend on ball speed, revs, and all that good stuff, but I don't have a lot of hand or ball speed most of the time, so smooth works very well for me.
