Fact is, since I switched to PS Energy from Tour Bite, my arm feels better and doesn't get "tired" like it used to. But I've never suffered from tennis elbow from any frame or string, but I've always used small (90-93 sq. in.), heavy (12+ oz.), headlight frames.
This is a great description of what my arm feels like with the wrong string. I strung up a set of Timo 18 I had laying around to try in my new frame. At 51/49, my arm was tight the next morning, tired feeling and I'm 54. The search continues...
