Hey fellow TW'ers I just got back from playing 4 sets with a brand new US K90. Although I've demo'd the racket before, today is the first day I've used it extensively in matches. I know I speak for the majority when I say match play is entirely different than rallying. Before I begin, here's the setup: US K90 Luxilon ALU Power Rough @ 50lbs (recommended tension is 50-60lbs) 3/8 grip (I normally use 1/2) Wilson Pro Overgrip (White) A little bit about me: I'm a 4.5 rated player with a 2-handed backhand and an all-court style of play. My 2hbh is my best shot as my forehand can break down in critical moments in a match. I mix my serves up with slice and kick, but being only 5'8 I rarely serve purely flat. Both my serves have heavy spin but I rarely get more than one ace per service game. I come in to volley on both serves, and I'm always looking for an opportunity to come in during a rally since I feel the most comfortable at the net. From the baseline, I hit heavy topspin from both wings but my slices are also very effective. I'll play a counter-punching style of play until an opportunity arrives to hit an approach shot and go to the net--I've always preferred a consistent, control oriented game to a power one. Solid lobbers and flat hitters are my greatest weakness. I usually use a Babolat Pure Drive + with Cortex, with 18 grams of lead tape in the upper hoop. My preferred string is Wilson NXT Tour @ 65lbs. It's definitely not the typical all-court racket, which is why I've been tempted to give the K90 a run. K90 Review: My initial impression when short-courting was shock--the K90 has that buttery feel on contact that I've rarely experienced, and I've owned classics such as the MW 200g, Classic Mid, i.Prestige, POG mid, among others. This type of feel only happens when using kevlar rackets, from my experience. But good feel or not doesn't matter, what matters is what translates into the ball. My PD+ @ 65lbs with ALU Power rough is extremely stiff and dead on the arm, but what it does to the ball is amazing. That soft touch does wonders for your confidence however... Serves: My serves had just as much spin as my PD+, but less penetration. Finding placement was much easier than on the PD+ however, and I found myself getting many cheap points kicking it high and wide to the backhand. I suspect that even when I am fully comfortable with the K90, my serves will never be as heavy as with the PD+. Definitely one of the better rackets on serve, but comparing it to perhaps the best line of rackets for serving is a bit unfair. 6-8 grams of lead tape in the upper hoop and this racket will definitely benefit on the serve. 88/100. [PD+: 95/100] Groundstrokes: That buttery feel of the racket translated into deep, heavy spinning balls with excellent placement. Generating spin with this racket was just as easy as with the PD+, but the control and confidence level with the racket is on an entirely different level. It really whips through the air, letting you get some nice spin and control on the ball at the same time. I won't say I could place the ball on a dime (I never can), but control was never an issue as it was at times with the PD+. My backhand suffered a bit from using this racket because I just couldn't generate the same amount as power as I could before. What used to be a winner was now just a well placed approach shot that needed one more stroke to finish off. This occurred even though I strung the K90 15lbs less than I do with the PD+. At least the placement was better with the backhand though, I was much more confident in the second serve down-the-line doubles return. Slices with this racket, as most people say, are amazing. The pocketing this racket does with the ball really lets you guide through the ball on the slice, and the spin was equally devastating. The downside of this racket is definitely its unforgiving nature. For a players racket though, it is surprisingly forgiving, but you still need to have good footwork on every shot if you want your ball to have pace. I couldn't get away with the some of the lazy shots I unfortunately developed with the PD+. Still, groundstrokes with this racket are a pleasure. I give the K90 a slight edge because groundies are predictable and not as unwieldy as with the PD+. A power player will probably disagree with me here. 92/100 [PD+: 90/100]. Volleys: This is where the racket really shines. I could never hit a solid drop volley with the PD+, but again the pocketing you get with the K90 is unmatched. This racket slices through the air and is surprisingly stable even on off centered hits on the string bed. You can volley the ball deep, or pocket the ball at a sharp angle. Simply stunning volleying racket, I will go up to the net even more now. Even half-volleys improved with this racket because you can really guide the ball deep or angled with pocketing you get. I have no clue how this racket isn't less than a 67 stiffness rating, but that doesn't matter. 100/100 [PD+: 80/100] Returns: Not the best returning racket since you need good footwork and prep to hit a deep ball. The low power level means you need to take a good cut at the ball as well. Many of my returns fell short, but I was never worried about them getting poached because of the control. The only redeeming factor was returning second serves to the forehand--these were a real treat. The heaviness of the racket lets you block back flat bombs, but such is with most players rackets. I give the PD+ the edge because it is more forgiving. 85/100 [PD+ 88/100] Overall playing with the K90 is like driving a BMW on manual. It's a high performance racket and you can really take advantage of its features if you're good. If you're not, then it's a bit of a waste but still a pleasure to use. If you're purely a baseliner with a 2hbh, I definitely do not recommend this racket whether your 2h is good or not. There's little reason to use a mid, and perhaps even a standard length racket if you are a pure 2hbh baseliner, however there are control advantages with a 27in. If you're exceptionally strong though this will not be an issue. I can't speak for 1hbh'ers because this very well may be an excellent 1hbh racket. What I like most about this racket is it will improve your footwork and setup, and encourage you to come up to the net more often to finish off those easy points. Again the feel and pocketing of this racket is unparalleled and worth a demo just to experience for yourself. Definitely a "classic" racket worth entering the racket hall of fame. Thanks for reading and I hope you enjoyed this review!
