Mardy is using a 28 inch racket that weighs in at 13 oz. (366 grams). Grip size is 4 1/2 in. and head size is 95sq. in. String pattern is 18 by 20 with a poly in the mains and babolat gut in the crosses. He uses 6 powerpads. His name is painted on the frame at the 6 o'clock position. The racquet doesn't have the PWS system that Wilson rackets have, but when compared to the stock 300g it was clear that this was a wilson mold. So basically this is a 6.1 pro staff stretch that was discontinued a few years ago (red and yellow model). Dunlop is making this for him without the PWS on the sides of the frame. Hope that helps solve any mystery surrounding his racket. Tension I'm not sure about, but the strings were pretty tight, and the grip appeared to be custom. I may actually have a chance to hit with it later and if I do I'll give a full report. The swing weight on this thing must be rediculous though. Same racquet basically as the old 6.1 classic stretch 28 inch. All Dunlop did was match the weight of the old frame with an extremely similar mold. All that is missing is the PWS system.
