Ok, I am going to bowl a tournament on the blue pattern. Looking at the patterns, it can be 19+ ml volume or 27 + depending on which blue it is. 3.2 or 4.2 to 1 for the ratios. I have bowled on the PBAX as well as the city patterns, and am looking for any advice as far as surface goes. 27+ would allow me to throw balls that hook in oil (Destroyr, Maxx Zone, Terminator), but 19 changes to lighter pattern equipment (Big R Bang, Freeze Hybrid, Slingshot).
With the stronger balls, is surface the ticket or do I want to let the nature of the ball do it? Lighter, is a slingshot with surface it or try to create more roll? What have you had success with?

Bowled on this pattern twice in the same house. Synthetics not sure what.

For me getting in and hooking the ball was wide open. Used an Aura with 500/2000 surface but there were plenty of other options that would be just fine. Was looking at 25 to 10 anything outside of 10 was out of bounds. If you like playing outside the shot is there but very unforgiving. Moving in there is a lot more friction down lane and made for a much easier time.

Start off playing your normal line and then move right and left of there and see what you like.

Sounds like an inside line is a good place to start. I was wondering if playing out would force you to thread a needle. Thanks for the advice gentlemen.

Use the ball reaction rule

Trust your eyes.  For me, most sport shots (or almost sport shots) applied by centers who 99% of the time run house shots don't necessarily play as difficult compared to a weekend long tournament that runs the shot multiple times in a row.

Using length may tell you how to approach the shot, but don't ignore the center's normal track area.  Try a variety of lines and let your eyes tell you what to do.
