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.
But do you hit flat?
Yes, stringing poly at super low tensions can only help and using a heavy racquet always helps, too.
