The Primal Shock has the venom shock cover and the primal core. I've never thrown any of the primals but I've thrown venom shocks. And if you're a big fan of the venom shocks, then this ball is for you.
I've thrown the primal on both wood and synthetic lanes and it reacted completely different. I was playing farther left on wood lanes than synthetics. With that being said, the primal shock is very versatile and can play any part of the lane. On wood, playing further left, the primal still has energy on the backend. On synthetics, I was a little further right and when I had to move left, it still had energy on the backend.
The Primal Shock is a very versatile ball that can be used on any lane condition. I definitely recommend this ball.
