I have shoulder problems, too, and I don't think any racquet in the world would fix it: I tend to hit my toss way too far behind my head (errant/unpredictable toss). Over time, this would destroy anyone's shoulder, IMHO.
Actually this is exactly what happened to me as well. Once I fixed my toss and altered my form a little bit on my serve, my shoulder problems all but disappeared. So it may be worth while to try and figure out what exact movements in your strokes are causing your pain.
