... my bad thought you asked which is the best paradox to drill. lol
Without seeing you bowl, or knowing what kind of shot you'd be on with the ball, or what you want the ball to do... there's no telling the "best layout" for you.
With bowling equipment... the terms "Better" / "Worse" , "Best" , etc. are all OPINIONATED. It's different for everyone because everyone has different styles and bowl on different conditions.
Ask your proshop operator.... if you don't like him/her because a result was bad with previous equipment, then go to someone else or work out what went wrong with the priors.
Bowling is all trial and error. And when someone can't roll the ball consistently, it's almost impossible to further tailor equipment for them (not saying you)
