Now that I've had a good number of hours under my belt with the RF97, both in practice situations and matches, I thought I'd post my thoughts on it.
I'll start of with a disclaimer: I am currently under a work contract with Wilson. Having said that I've played with a Wilson Pro Staff racquet since the PS85 so I think I can objectively post this review and not be swayed by my recent work relationship with Wilson.
Racquet before switching to RF97
For the last year or so I started playing about half the time with a PS95S, and the other half the time with my trusty PS90. The PS95S was strung with 4G in the high 50's, while my PS90 was strung with champion choice around 50lb.
Setup of RF97
Initially I strung it up with Champions Choice using Federer's tension (59/56lb), but lately I've gone down to 56/53lb. I also have one frame strung with 4G but have not put much time on it at all so I'll keep my feedback to my experience with the Champions Choice strung frame. I've switched the Wilson leather grip to TW's 1.3mm leather grip (I like the thinner feel that gives better feel of the bevel edges) and then have Wilson Pro Overgrip on top.
Forehands
Let me start off with saying that I've been tweaking / changing my forehand lately so I'm not as dialled in / connected with that shot at the moment. Having said that I was blasting my forehands. The frame adds very noticeable extra power on that shot. I could also tell some increased spin I got with this over the PS90 (but maybe not quite as much as the PS95S). This is also the shot where I felt the increased size of the sweet-spot the most.... and it is much bigger. Maybe because I'm tinkering around with my forehand I needed a larger sweet-spot here more than on any other shot to give me that extra margin of error. Now, let me cover the most talked about issue: weight / swing weight. To me this is just 'slightly' (almost not noticeably) heavier than the PS90 but to be honest now that I've played with it for a month or so I can't really tell the difference. Compared to the K88 which I have played with a bit, the RF97 is
much easier to swing. The K88 is the only racquet that I really found heavy to swing.
Backhand
Love it! Instant added plow-through on the topspin backhand! Heavy ball on the slice. I was able to abbreviate my backswing on the slice and still get a hard and biting ball ... in the end I think my slice backhand is now a better shot technically too as a result. I think the only shot that I'm still not totally dialled into is a heavy topspin backhand, not sure really why but it might be just the slight extra swing weight, but I'm finding my backhands to be flatter with this frame. My favorite shot with this racquet overall is a block/flat backhand hit off a heavy and deep ball from my opponent. That ball that bounces just inside the baseline... I'm able to basically half volley it from there with almost no backswing and just letting the frame's weight, stability and increased sweetspot do all the work.
Volleys
Very solid. I tend to take a little bit too much of a swing at some of my volleys so just like the slice backhand this racquet is actually helping my volley technique as I can take a much shorter 'punch' at the ball and get some sweet pace and bite. A 12oz "game improvement" frame?
.... maybe for me with my long swings.
Serves
From day one with this racquet my serves have been huge! The first match I played with the racquet I hit more aces that I had done in any match in my life. The extra power is the most noticeable here for me. One the downside, I'm still not quite there with heavier spin second serves. I'm finding they tend to fly a bit long. I'm getting them in range a bit better lately, but it is a work in progress still.
Returns
As I mentioned before I have quite long / loopy swings, and they have always been my achilles on service returns. It's always been the weakest part of my game especially on the forehand. With the RF97 I'm still struggling with the forehand return. I think if I really shorten my swing the stability and weight of the racquet would help here, but I'm not there yet. However on the backhand where I do tend to chip the ball often, things are going much better. The returns have more depth and bite on them so I'm pretty happy there.
Overall
Very happy with this frame. It was a pretty easy, but very welcome transition from my PS90. I'm using the RF97 as my main frame and loving it more every day. Yes, it's taken a bit to get used to the fact that I'm not holding a thin, box-beam, and smaller frame in my hand, but I think I'm OK with that now and just enjoying the extra benefits I get with this frame. As for the cosmetics.... well I'm sure they'll grow on me in time
