No reason to have the S70 for the simple fact our Black Ops has been selling like crazy. The "X" should give us more motion than the Chemical X which for me can be an awesome thing. Thinking this one is going to fit right between the Chemical X and The Respect Solid in terms of solid symmetrical cores. Black Ops is basically in the same spot, but with a way different motion with the asymmetrical core. Should have the "X" in by next week to do some testing.
