here is a little skinny for you guys regarding the cover and core combo. first off the core is the same as the original Guru, identical numbers, shape and density. secondly the cover is the same base resin formula. So how does it perform so differently you may ask.
We dye our resins we do not use pigment so there is no impact of color on the performance of our shells. We do use additives to get the desired length and shape regarding ball motion.
When you look at the ball it will have a solid blue and a pearl "looking" green color combo. In reality they are both the same resin, its esthetic only. We used an additive combination to create the exact motion. If we desired we could make a solid black ball roll exactly like a skid flip pearl. This is the newest technology in the market. that is why the Guru does what it does and why the new Guru can actually offer a totally new performance, it is a great ball and I guarantee you will all be pleasantly surprised.
