This is the best bang for your buck when it comes to asymmetric and over all hook potential. This ball is one of the most hard hitting balls I've ever thrown. When this ball hits the pins it grabs everyones attention. The Track Kinetic glides thru the front end and responds very well down lane. It gives you a sharper entry angle to the pocket with control. Due to the modified Kinetic asymmetric core. As the Track Mako starts to eat up the oil. The Track Kinetic takes over and delivers a great 1-2 punch and devour your competion. Both the Mako and Kinetic will perform well together on your typical house shot and also the Open Championships.

It's not that cut and dry, it's certainly part of the equation
I was on a factory tour a few months ago and they talked about it
The eruption pro hybrid, slower responding cover, red & orange
The kinetic emerald, green and black, quicker responding cover for me
The blue tundra, quicker responding for me
The track heat, slower response for me
I don't know all the details by any means, but color does play a bigger role these days in the cover technology than in the past

It's what we were told at the factory
And by others we met there
Tend to believe the place that makes them

I picked up a Kinetic Emerald last night.  My thoughts on a limited sample size of shots:

- It's more arcing than skid/flip.  Speaking in terms of newer releases, the Kinetic Emerald's ball motion reminds me of the Eternal Cell.  Very smooth for a polished ball, even in the dry the ball did not make a sudden change in direction.

- I have the same layout on it as the Code Black and the Code Black goes more sideways off the spot while covering just about the same amount of boards.  I now have two options for different ball motions in the same range of hook potential depending on what the lane is dictating.

- In terms of total hook potential, it feels like a true medium ball to me.  In terms of my arsenal, it slots above the HyRoad, next to Code Black, and below the Phaze II.  On nights that I start with the Phaze II, I can see the potential of stepping down to the Kinetic Emerald without having to move (how nice is it to be lefty?).
