Used an Aero200 that weighed 12.7 oz strung for one year.
I needed to shorten and quicken my swing to compensate for the weight, so most of my shots easily landed in. I still have it, and use it once a month, or twice, just to remind myself I went the right direction (I went to 500's).
Since I'm old, injured, crippled, and somewhat blind, that racket really taxed my physical skills, and playing the 3rd singles or 5th doubles sets, I was totally worn out and couldn't walk straight on the way home.
But if you can handle the weight, swing it fast and easy even after a couple hours on court, it does give great control, feel, and a distain for any kind of incoming ball.
