context: After 18 years away from the game I'm a 3.5 tuning up to 4.0. Still playing my Wilson Sting, 12.5oz, 88". Big Hitter Blue Rough 17 mains / Gosen 17 crosses. Demoing another group of racquets from TW. First session today and just wanted to rotate through them all for initial impressions. Dunlop Aerogel 4d 300 Tour: 20 minutes. Groundstrokes: felt solid, predictable, not too powerful but able to generate pace when needed, fast swinging, felt good on my SHBH. Volleys: quick to position, solid and nice feel. Serve: Great pace on first serves, decent spin on second serves. Haven't worked out the timing completely but feel I could dial this one in quickly. Will turn up the topspin volume next time out and see how much kick I can generate. General: This is very promising. Feels like a more forgiving ag100 with better volley performance and (I think) better serve performance. donnay x-red 99: 10 minutes. General: demo came with what I consider a terrible hybrid string setup that somehow managed to feel super tight and at the same time overpowered. I HATED it. But I'm pretty sure it isn't the frame's fault. I don't think I know where to go from here. Now what? ProKennex Black Ace 98: 5 minutes. Volleys: solid and rewarding. Groundstrokes: I found it tremendously difficult to get this thing moving, was hitting all my balls late, especially backhand. General: Kind of felt pointless. I want a relatively light racquet that plays heavy but doesn't feel heavy. This racquet just felt slow and cumbersome and that's coming from a guy who normally plays a 12.5oz frame. There is no reason this frame should feel like it does. Based on reputation I had high hopes for this frame. I will invest more time before setting it aside so that the PK groupies won't put a curse on me. Pacific x Force Pro: 10 minutes. Groundstrokes: Lots of relatively manageable power. Felt a lot like my old Prince Graphite II OS. Easy to swing, came around quick on backhands, good spin, easy to send the ball long which I did with aplomb. Volleys: not yet. Serve: not yet. Return: not yet. General: Intriguing. Reminds me of the Babolat Roddick GT. Probably too much power and elbow pain for me. Out of the 8 racquets I have under consideration right now the current leaders are: Boris Becker London, Dunlop ag300 tour, Wilson BLX Blade 98. I will update this thread after more court time this week.
