pin up,low flair, light load particle ball or strong arcing rective. take your hand out of the ball. go up the oil line. adjust surafces to match your speed and release.
most can not swing through backend oil. straighter is greater. the idea is to delay the transition from skid to hook until you clear the heads and then some. if you can get a med strong particle to skid by hand postions the shell will take over in the mid/backend slop.
a ball like the big Kahuna, phenom unleased, rule etc can work.
personally I like to fluff a particel ball and trust it. sloppy lanes do not take me out of play. I do that all by myself
