Razor code was on sale at the TW tent at IW so I picked up a bunch, here are some initial thoughts. The two biggest positives are the pop and the slice. + The string has a ton of pop on groundstrokes and the serve. Definitely a very lively poly and will allow players to hit some flat serve and forehand bombs. At 53 tension I could feel the ball explode off the string bed. + This string creates some nasty slice. On the serve my second serve was moving my opponent all over the court. On the backhand slice I could move my opponent side to side on the court. Also threw in some forehand slice returns. Probably the best slicing poly ive ever used. + Feel; I was hitting some nice touch shots with this poly. Hit a few drop shots that stopped on a dime and was able to place approach shots where i wanted. - Not as spin friendly as most polys, I'd say its below average for poly spin. - There is also a lack of control, it turned my racquet into a rocket launcher when my opponent was hitting a heavy ball. So far I'd give it an 8.5/10. I'd say I like it better than black code, and find it more similar to red code but with more pop. I still prefer my favorite poly (solinco outlast) to this but I will play with it more later in the week.
