I ordered one a few weeks ago and finally got a chance to hit with it a little bit, about two hours of training and an hour of match play. Not a lot of time yet, but it has already made an impression. Two words come to mind:
Stability: Probably the best blade I've owned for blocking. It feels firm without being hard, like an old-school memory foam mattress. There are no jarring sensations when meeting a powerful ball. This makes passive blocking a breeze and active blocking easier to control. My coach, who normally excoriates me for my inconsistent blocking, was borderline ecstatic during block practice. Hopefully it wasn't a fluke performance on my part...
Feedback: The hand feel is probably my favorite aspect so far. It gives an "Ah, that's where I hit it" sensation, more toward the index finger, rather than a jarring vibration if you hit outside the sweet spot; and when you nail the ball on-target it just feels natural. (And produces a beautiful ball trajectory.)
Coming from inner carbon as my main blade I was a little nervous that the outer-fiber structure would make it too fast for my taste, but while it is a bit quicker than my JRE it is not a speed monster. I would not rate it as fast as a Viscaria; maybe around the HL5. The speed is more apparent a step away from the table and it has not felt too fast for me to handle. I can see why people say it pairs well with harder rubbers for that extra oomph. It has the control to be a deadly weapon with these newer-generation ESN hybrids. I tend to play closer to the table, though, and am currently satisfied with medium-hard rubbers on both sides (Gold Arc 8 on FH and Vega Pro H on BH, both 47.5°). It would probably pair well with good ol' T05 too, if that's your thing.
