If you use multifilament to take care of your arm on your current racquet you should try the 98D, I thought it was nice, but i preferred 97T, bigger sweet spot than 98d, or you can go with Ezone Xi, this is a arm friendly racquet, you may like it, though it is a cannon if you don't have the right tension for it.
Yeah, there is a huge following with 89t, but you could be fine with 98d , 97t 310g or Ezone Xi.
