low, late, flaring ball that should react more or less on the backend of the lane.
a arcing ball will arc sonner and have less backend.
a snap ball will be a little less snappy. probably not an arc but come out of the oil with core in a more friedly postion if you have hand.
a lot depends on the oil pattern. if you have heavy oil and dry backens you can get some BIG snap out of some resins and no layout is going to improve it by that much.
