I demo'd the Aerogel 300 last night for about 20mins of solid hitting and i must say, it is a very good stick. It was strung with Dunlop Multi by the factory, at around mid to high 50's from what i could tell. It felt good in my hands, the grip shape was well bevelled and comfortable. Swinging it was a pleasure, it had a nice solid feel through the air and at impact it just ploughed through the ball. It had a great solid sound at impact on all strokes, and seemed to have just the right amount of flex, control and controllable power. I've never picked up a racquet and not felt so comfortable right away. It didn't feel like a lighter racquet to me at all, probably due to the balance being nearly even? The head shape is a little more rectangular than previous models, it actually reminded me of a psuedo Yonex racquet! I've always been a fan of constant beam racquets and this one gives the impression to me of a lighter players frame. Conclusion: It is an excellent racquet for anyone, either starting tennis, intermediates or even a great platform for modifications and tweaking by stronger players. One of the most impressive racquets i've played with. I'm going to demo the 200 when i get a chance.
