I found rakza 7 had a grippy/tacky surface which meant that the balls dwell time on the rubber was a fraction longer so you were able to impart good spin with a nice ark. Its a very nice rubber to serve with as I was able to get great control and grippy spin and all my serves benefited from this as over time it helped improve my service as I was able to get more spin than previous rubbers.
It is a tensor type rubber so is fast. It is not quite as fast as tenergy but would be well suited to aggressive players looking for a bit more spin on their loops and especially serves. Rakza 7, I found, was better for serving and control than tenergy because of this tacky surface and yet still offered power that was similar to tenergy.
