The skid/flip is a great drill for this ball, without knowing a LOT more info it's hard to give you any good advise. Look at the #2 drill, placing the pin 4 3/4 from your PAP, pin under or just under and right of RF. I've done several of these and they seem to work well for those with a bit slower ball speeds.
One thing I will say, if your driller does not know your PAP or does not find it before drilling, only luck be with you if the ball turns out well. A PAP is very important info when drilling the BW line.
JMO.
Good Luck !
