Reading these posts makes me sooo glad I don't have a bad case of TE even when I still have a one-handed backhand. I have a mostly under control, passive case of tennis elbow but it was never from the backhand side. It seems to mostly come up now from the serve if anything.
Feel no pain, only occasional 'numb irritation' if I'm careless, and I can use a full bed of a softer poly or hybrid. But I need some form of dampening. Whether built-in or added by myself. For context, low stiffness and the ATS Textreme with Twaron seems to work for me, but I can get by with the VDM from Yonex if I modify with a bit more dampening and a not too stiff or uncomfortable poly.
I would strongly suggest some people here experiment with adding some type of foam into one side of the chambers in a racquet handle, the some type of foam packing tape into the other to even out the weight but not dampen feel too much, maybe power pads, and electrical tape instead of lead tape for adding weight. Luckily I don't seem to be sensitive to strict static weight limits.
Stick to multis with some poly inside for the mains if possible, Prince Premier Control, Head Velocity, Tecnifibre Triax are good ones. I've wondered about adding D3O foam tape under or into a handle before but I never got there since I didn't need to anymore.
Recommend looking up scraping or whatever it's called, or other massage techniques for recovering from the damage already caused, time away will very likely never be enough. The tendons have already sustained structural damage and denaturing.
