Now the Katana is really interesting. That's a pearl, first time they've introduced a high-end asymmetric line with one I believe. Specs for 15 pounds are 2.503 RG, 0.050 DIF, and 0.020 MB. Pegged as the most angular ball they've made.
The coverstock actually has a name too for the first time in Radical history. This one is Forged. Will be interesting to see if this trend continues and then we can actually tell when a specific coverstock is reused for other balls.
