I saw a Radical staffer using an Uncaged last night in league and in pot games. I'm not surprised at all that it appears to perform better than the Unleashed and Untamed. The Uncaged kind of reminds me of reactive pearl pieces from 20 years ago when it gave scratch bowlers like myself that wow factor, realizing that I now had an extra board to work with on the lanes.
What I shared with him, though, it seems that Radical's pearl pieces seem to be more, for a lack of a better word, livelier, and versatile than their solids. Maybe this is something that Phil can explain.
