sorry bud but 99% of the fakes are 4 1/4 grip size. based on the other things you have noticed i would put money on it being fake. does it swing or feel different than your other racquets?
i havent been able to get on a actual tennis court yet but i have tried to hit around in a racquetball court with it and when i swing with it, it feels very similar to my other 2 legit aeropro drive racquets.. all the other specs of the racquet is similar to my other 2 aeropro drive racquets the only difference i see is the aeropro logo on the throat is missing.. also i seen this article on 3bay which showed the structure inside the handle where they showed a fake babolat compared to a real and when i opened the buttcap for the one i have purchased it looks exactly like the real one.. here is the link..
here is the actual link to the post on 3bay..

also i'd like to note that the texture of the bag and strap is identical to the one i have and the color is right on.. also the bag has a imprint "Aeropro" on the bag also.. but the bag doesnt have the Aeropro sign also on the top of the bag.. the zippers on the bag has the babolat sign also.
thank you for your opinions! Any information is appriciated!
