Sonic Pro proved to be a little livelier than the polys we typically use. The slight bump in power worked just fine for Troy. He said, “I found the power level of this string to be slightly higher than average for a co-poly string. It was fairly crisp and firm right off the stringer, but after a solid hour of hitting it softened up and felt livelier. I enjoyed the power of this string because it had just enough pop while still maintaining good control.
