Tried the 4UG5 version. Looks stunning imo, more of a matte dark grey than black with nice and subtle orange and red accents. Overall good racket, fast enough for a HH racket, and quite powerful. Would need more hours with it the write a more elaborate review. Compared to my favorite rackets of recent years (mainly BS12 and the new Panda Power Ppro Prototype), it is clearly not as fast and not as easy to generate decent power. It probably can generate more power but with much more effort. I think that playing several years with the BS12 spoiled me in a way, that I just can't like or feel comfortable with any significantly stiffer rackets.
