Mine would have to be either the Head IG Prestige Pro. This racquet does it all. Hits flat well. Spins the ball well. Stable, the right weight for me. Plenty of plow, control on the drives. Great serving racquet, nice cuts on the volleys.
The only thing that happened on my demo is the clear bumper guard came off on one of my backhand slices. I don't know if the material is not as strong as the standard black ones of last year and the years before. But I've never had it peel apart from the center of the top like that.
My close second is the Tecnifibre 325 VO2 max. I'd need a touch of lead so it would plow as well. The volleys all have to be sheared with back spin more than the Prestige Pro. Hitting them flat does launch them more, with a faster rebound angle. But everything else is great.
