hey jess,
well.. i have an acid also and i got it layed out 4x4, and am a stroker for the most part. i like my acid, but its really lane specific for me. i got mine down to 1000 abralon or maybe 2000 grit, and on fresh oil, i get some over/under with it, but i think its due to the way i throw, im kinda rev challenged, but i found mine to work best when the lanes are drier. but to answer your question, i think having the pin slightly below the ring finger with the cg kicked out, or place the pin closer to the pap (strong position), and that should help. of course it also depends on how fast she throws the ball, release, etc.
good luck.
p.s. im starting to like my acid, i just need to find the right conditions, just like with any ball. also you can always get her a hammer jacked, bw nasty, jigsaw, or corner.
