I need some advice as to what the best ball is for heavy oil patterns. I am a high speed medium rev down and in bowler. I had the 900 global bank roll because it was a really low rg ball, but still wasn't getting the results I'd hoped to. Also, would an early hooking layout be better than a more arcing layout? Pin down rather than pin up? Help! I'm relatively new to bowling and need some solid advice.... Thanks!!

Also keep in mind that "heavy oil balls" don't cover boards.  Many people buy heavy oil balls and are disappointed because they don't cover as many boards as their other pieces.  Heavy oil balls don't respond to friction as fast as other balls because they bleed energy much faster in the midlane.

The main patterns I am concerned with are the one's used at our state tournament. Usually either the red, white, or blue pattern. Our THS is generally very short but moderately heavy oil, especially to the outside.Also, would a higher RG ball be better since it reacts more aggressively off of the dry, or a low RG ball that revs sooner?

here is actual data from a class that I attended

the factors that influence a ball motion are:

coverstock - 50% of total reaction
core type - 20% of total reaction
texture - 15% of total reaction
layout & tweaks - 15% of total reaction

the above data is from a very knowledgeable person in the industry

Track 912T is a heavy oil ball

I threw it a demo days last fall on a fairly heavy oil pattern, It is to much ball for me, although i have a higher rev rate and axis tilt.
It takes to surfaces changes very well
