Layout: 60 degrees x 5" x 40 degrees RG: 2.57" Differential: .046" Surface: 4000 grit sanded Core shape: Symmetric What I wanted from this ball: I was looking for an even rolling, smooth symmetric option. I didn't have many symmetric core balls in my bag at this time, and I thought the All Road would be a good choice to tryout something different. It's not often that you'll find a higher rg core system in a smooth sanded cover, so I was eager to take a peek at the All Road.
