I'd add one thing that I have noticed on most if not all PBA-type patterns:
All the oil patterns seem to react the safest, when you ball speed and release are extremely consistent. You can be slightly off in targetting, as long as the other two are steady. When your speeds vary, slow speed results in early and too much hook. Faster speed results in too much skid and too late a ball break, almost every time, without fail.
One other item. Except for occasional moments of carrydown, most times, balls with big backends seem to be a handicap, as opposed to on house shots, where they are mostly a benefit. Balls with a controlled backend seem to provide a major benefit, because the backends very often act very clean, as if they were freshly stripped.
This is specially true for your balls which are mostly asymmetric. You did not mention how they are drilled. Your previous non-success may be related to the combination of surface and drill.I'd check with Rick and Carl on the drills for PBA patterns. They, expeically for a cranker, should probably be fairly different from drills for house shots.
