First impressions: very nice pimple structure in terms of size, spacing and alignment (vertically aligned) and excellently grippy topsheet. Topsheet has a mild tack to it, and spins as much as a sheet of higher. The bounce is rather low, very controlled. Hopefully as the tack wears off the bounce will improve. At the moment it is looking like a great FH rubber...(but I was looking for a BH rubber...err..). Sponge is nice and I'd put it at mid-soft, a tad softer than normal Bryce.

First of all, definately slower than Sriver. Sriver, although not being a super fast rubber itself, had a nice med-hard sponge at around 40 degrees. This was beautifully linear, that is, I would get as much power as I put in. Unfortunately I feel the 34-36 sponge of the Rapid Power combined with whatever they did to get that nice click sound (yes, I did manage to hit hard enough for a loud click even on a Hurricane King) has made the rubber slow on the top gears. To generate the blazingly fast topspin, you really need to take it off the bounce and rip the ball with maximum wrist in a forward direction with a closed angle (just as what JKC has said many times Razz).

Its tack wore off quickly as dust gathered on the topsheet, although a quick clean returns that beautiful grip that I knew would remain.

Over the table, it is really nice. It's got the liveliness of japanese rubber, but being on the slow side, much better control for flips and the short game. Even half-long balls can be punished with a heavy topspin loop, although killing such a serve/push proved difficult as the rubber has just too much dwell and favoured a spinny loop as opposed to a speed one.

Its biggest weakness would be blocking, you have to be careful that you're not just sticking your racket out, as the slow speed would send the ball into the net, but if you countered every ball, it would fly off the table. So the stroke I found to work nicely is that disgusting Oh Sang Eun block, where you're pushing forward but the motion is left to right. That adds some nasty sidespin to the ball and keeps it very controlled, so that you may rip the next one off the bounce.

All in all, SPEED is decent: you gotta be courageous enough to rip off the bounce to kill, SPIN is pretty good: closer to the jap stuff, but had more control, PUSHING is low and controlled, FLIPPING is nice and accurate, BLOCKING just needs a little getting used to. But I think I've found a really cheap alternative to the "classic" rubbers, and for its price, I'd say the adjustment is well worth it.
