The Decree Pearl has Composite Fang Pearl cover stock and the Command Symmetric core.. I liked the numbers RG 2.530 DIFF 0.043, so I drilled this pin down 50x4.5x75. The numbers say for light to medium oil. compared to the solid(which I drilled pin up) so can't really compare then. but with that said, I was able to play right with a little swing room with no over under on THS. Will be interesting to see the reaction on a 35-39ft pattern or broken down lanes
