OK- I've tried all of the demos for a couple of days now, and I've posted my personal findings below(feel free to skip the paragraph and go to the abbreviated line at the bottom of each review:
Wilson Pro Staff 90:
This racquet hadn't disappointed me yet, so this was probably the demo I was most looking forward to. The first one I received had been freshly strung with Lux. savage, and played the best of the first two demos, so when I saw this one had savage, I was also excited. I think TW must have strung it lower,and/or more people had used that stringjob before me. I agree with many people who have tried this one-- the racquet is sensitive to string setup. I'm still liking the way it plays but not quite as much as with the fresh stringjob. The cheap overgrip on this one doesn't help either, but that's an easy fix. While the racquet is hefty, if I warm up it is manageable, and the extra mass really helps with my 2hbackhand, which is surprising given how many people posted reviews saying it was really best for 1h backhands. Off the forehand side I can crush shots with confidence. Serves take getting used to-- you have to be generating power correctly or you will destroy your arm, but the control is excellent. My favorite part of this racquet has to be the volleying. The control at the net of this stick really puts it in a class of its own (of those I've tried!)
I think this frame is excellent if you can make the most of its control (consistently.) It doesn't play as heavy as it is, and it also seems to be a forgiving frame for a 90" headsize.
Wilson Blade 93 (2013):
I was really eager to get my hands on this demo, since it released a few months back. Feelings so far are mixed. The power this frame generates, especially for a mid, is pretty good. The denser string pattern helps with control, and allows shots to be flatter.
Now to the negatives: The frame is marketed as a sort of "Next Gen" Mid-- with the modern game in mind. I suppose this explains the stiffness (listed at 67 by TW but it felt much stiffer than any of my other demos.) Interestingly, it seems to have some other attributes of the "old-school" mids-- the dense string pattern wouldn't be great for those who want maximum spin (I'm fine with the dense or open pattern, honestly.) The other thing that really doesn't get enough attention about this frame is that the grip is short. I'm used to a longer-than-standard handle on the Juice Pro, but even the handles of the Pro Staff 90, Prestige Mid and Radical Pro were much more spacious than the Blade 93. It seems ludicrous that a company would claim a racquet be for the "modern game" yet make it difficult to use for 2h backhands. I think this frame could also have used just a tad more weight, but this wasn't a huge problem. I think this frame continues the problems of the previous blades-- it isn't able to fully cater to a player base. It feels like the unwanted offspring of a stiff Babolat frame and a "old school" mid, and the result ain't pretty.
I think that this is a frame that Wilson needs to improve upon. Keep the 18x20 pattern, and the 93" headsize, but give the racquet at least a standard handle, if not a longer-than standard handle (like the Juice Pro has.) Bring the weight up to 12.3 oz or so, keep the balance the same. Then they'll have a "next gen" frame.
Head Prestige Mid(2012)
This frame had a really nice feel to it. It is a tad lighter than the Pro Staff 90, and is a great control frame with the 18x20 string pattern. Groundstrokes are very similarly solid, although I didn't get quite as much pace on my backhand from this one as I did the 90. Felt just a tad less solid at net for me (I think the beam width and slightly lower weight had me feeling this way, but it was a very slight difference.) Serves were a tad easier with this one than the Pro Staff, but still had the mid feel. Overall this frame plays excellent, I just liked the Pro Staff 90 a tad better (I would be happy with either honestly, but I'm fortunate enough to have a choice!)
Head Radical Pro (2012)
This racquet is a solid frame from the baseline. A little light for me, but that can be easily fixed. I would definitely add the weight to the handle though, as the balance is more head-heavy than I am used to. Forehands seem to be the best shot with this one... Volleys weren't my favorite.
A good frame, but not quite the type I am looking for. I could work with it and make it very likeable, but there are others that were designed to have the weight and balance I am looking for.
Wilson Juice Pro
My current frame, I picked it a year ago at the start of my senior season. I've grown a fair amount since then (3 inches and about 15 lbs), and my tennis abilities have improved as well. I love the longer handle on this one for 2h backhands, and the weight and balance seemed to be good. (Having gotten stronger it's a tad light now, but that's a fairly easily fixed problem.) The unique part about this frame is that while its specifications are very similar to a Six one 95, the Juice Pro has a lot more power to it than any of those frames. As a result, I sometimes feel too tentative to really swing out and trust that the ball will stay in the court. This one feels like a mix of a six one 95 with the power (and extended length, although this is very slight) of a Pure Drive Roddick.
Another good offering from Wilson, and I like where they are going with this one, but it's a tad light, and more significantly for me, a frame that is powerful when I don't need it to be (It's tough to control at times.) Still a good frame though.
