There is also another style. I am not sure if these rackets have any meaningful differences other than the paint job.

This racket has a bit of intrigue to it. If you were to look closely at this picture of Ramy Ashour from squashpics.com you’d see the paintjob of the racket is identical to the Dunlop Aerogel 4D Max:
However, in the picture, the strings on Ramy’s racket narrow as they get closer to the throat. The 4D Max, on the other hand, has a straight string pattern.
But his racket’s been painted to look like the Dunlop Aerogel 4D Max. Why go to the trouble of changing the paint job, if the racket is commercially available? Who knows. Perhaps Ramy has very specific tastes and Dunlop has created a custom racket for him but made it to look like one of their commercially available models. In any case, we know Ramy Ashour is sponsored by Dunlop!
Update #2: This picture of Ramy at the 2012 El Gouna International shows Ramy holding a Biomimetic Max racket. At the very least, his paint job has been updated.
Update #3: I created a dedicated page, Ramy Ashour Racket, to track what Ramy is playing with. You’ll have to go there to see the latest.
