In the tournaments I bowl in we rarely see heavy oil, and when we do, it's SOUP, so it doesn't matter what ball you're using, you still have to point it off the corner.
I would make sure to take something weak in your bag. Been many a time, when I've cashed using a Tropical Storm or Super Beast, when everyone else can't keep their hooking monsters on the left or right side of the headpin.
Just an option for you.
