Manufacturers are under a lot of pressure to come out with balls that the public wants, and much of the buying public wants ever stronger hook monsters. Most of these super strong balls are not very useful to top caliber scratch bowlers in box condition. In addition core shell matchup is important, and again the manufacturers often go over the top with super aggressive shells wrapped around super strong asymmetrical cores. Best example from storm was the Nano series, but their have been others.
I am not familiar with the Crux, but the Lock, similar to the Paradox from Track, seems to have a core shell matchup that is very conducive tweaking for individual needs.
