Evermore aggressive bowling balls and the bowling industry...

I am a little irritated, I would like to see medium oil and light oil balls that have monster cores in them so they don't hook early but when they do they create a lot of revs.

You mean like the Marauder, Terror and Nexxxus? They hook late. The ball doesn't create the revs (for the most part, drilling can help) the bowler does.

Those type of balls are known as Pearls and Hybrids. Like Billf's example's.

aren't those heavy oil balls?

Marauder is medium. Terror medium to heavy. Nexxxus is also medium to heavy.
Plus their polish lets them clear the heads at an acceptable level as the oil dries out.
