The rdis100mp is a very nice racquet to play with. Unfortunately it is also very stiff. Some say it is stiffer than the specs given. I bought the rdis200mp, since it has the same specs except the stiffness (I had similar problems to yours). For some reason the weight distribution, and more importantly the power level felt different. If you are interested in trying the "softer version" of your current racquet, be sure to string it a couple of pounds tighter.
You should also try altering cold and warm water in 15 second intervals to improve elbows blood supply.
