With the new rules eliminating balance holes, asymmetric cored balls will be the best way to get the layout that you need.

However, current asymmetric balls are geared towards those who need a strong ball. For a number of bowlers, these balls are too strong for playing the typical house shot. An asymmetric cored ball with medium differentials and medium cover would be better.

The first company to produce a benchmark asymmetric ball wins!

Track Kinetic Emerald might be an option as well.

The Kinetics, Honey Badger, and Matrix don't count as asyms. The Code X, Black Ops series, do count.

DV8 Hitman Enforcer, Radical Ludicrous, Track Precision. All Asymmetric balls that could be considered benchmark balls.

I think of "strong" as front to back but I think people refer to "strong" as side motion. So I never really understand a question or statement with the word "strong" in it.

Lit Pearl despite the numbers and the "pearl" has a very Benchmark type shape for a high end ball. It's clean and smooth and responds to speed adjustments really well. Logix is also a great ball for medium-ish THS. It's also clean and smooth downlane. They are very forgiving off the dry because they don't jack knife left, but they can still cover a big amount of boards for a pearl.  I'm surprised how well both of these balls roll on the fresh for me.

This is going to sound nuts, but I'll go with a Black Ops, 50*5*65 with 2000. I know exactly which way to go from there.

I didn't think of it as a benchmark originally, but being lower tilt my DV8 Creed really acts as a benchmark ball for me. Easy to see if it works or what I can change to. DV8 has also had the Vandal series which all seemed to be more middle of the road. If you're higher in tilt or rotation maybe a little too sideways

Yes, I have higher tilt and higher rotation - need more control usually.
