Played with it last night for the 1st time.
After the obligitory period of adjustment (felt like I'd spent the last week in lunar gravity), things started to really come together.
There seemed to be very little loss in speed from my old (fast, carbon) blade, but I had much better ability to place the ball where I wanted. Blocking was the only area which seemed better on the old blade; loops, kills, and short drops all improved for me. I could execute a reasonable chop when needed and lobs were WAAAYYY easier now.
Am I happy with this blade? Oh yea.
