Hyroad series. Honey Badger.

Quantum Bias - asym.
Poison - sym.

You can still find a few Lane Masters balls that are two piece. I think there are four Hy-road balls currently available too. Brunswick not only has the Quantum Bias but Buddies still has the classic black quantum on their website in the sale section if you want a 14 or 15.

All the "Badgers" (there's 4 of them) from 900 Global are 2-piece balls---2 asymmetric and 2 symmetric

The largest issue for bowlers that use different weights in 2 piece design.  The bowler must be aware of different performance when selecting the ball weight and how to layout to get good performance.  I get the idea that many bowlers don't even consider this.  IMO this is a huge mistake.

16 lb. 900G Honey Badger 2.52 .054 .011
15 lb. 900G Honey Badger 2.57 .041 .008
14 lb. 900G Honey Badger 2.64 .020 .003

Quantum and Poison maintain dynamic integrity 14-16. The only way to do it is design 3 cores.

Can't speak to 14lb but can say from experience even though the diff of a 16lb Hy-Road Pearl is much larger it will still hook less than a 15lb OG Hy-Road at least for me.  Coverstock still is the more important consideration but yes one drawback to 2 piece balls is often the differences in the core between weights or even a lack of the lighter weights.

Since I use 14 lb. I can speak to the difference in the majority of 2 piece designs.  I applaud manufacturers that do design different 2 piece weight blocks to keep the integrity if the designed ball.  LM/L/LF don't even put out 16lb and 14 lb. information you have to dig that info. out of CAL Bowling which I have done with help from them.

In the OG Storm Hy-Roads it's exactly what I seek but in most other 2 piece designs 14 lb. are woefully lacking in total differential this means a 14 lb. user would have to use much different pin to PAP distance than 15 lb. users.  Being that I will do the research I tend to shy away from these specific balls and don't consider them.  The 900G Badger line would be one such line as an example. For those that don't do the research and then find through usage that a ball didn't perform for them as expected that could be one large reason.
