As I demo'd the black 16x19 tonight I recalled this thread and understood why you asked! One of the best all around stock demo's I've ever tried. There were two, one multi and one poly, both felt great, never thought it needed lead anywhere (can't remember the last time I felt that way about a 325g stick!)
Has that pure Radical feeling but quite a bit more pop, super solid and a very nice, plush feel. It does have some extra power that when I wasn't in attack mode I had to be a "tad" mindful of, but for a first hit it was hardly an issue. Enough to make me curious about the 18x20 though.
