The new 900 Global Origin features the brand new Ellipse AI core and RB93 Hybrid cover. I drilled mine 5 x 4 x 2 and after throwing this ball for awhile, it will probably be a staple in my bag as the first asymmetrical ball out of my bag once the lanes transition. Its cleaner and more angular than the new Attention Star S2 with more pop down lane. It really allows me to open my angles up and bridges the gap between the other asymmetrical balls in the SPI line up with the symmetrical ones. I think this ball will be very popular on house condition as well because of the motion it makes.
