Sarcasm, I am guessing?Who are all these wimps struggling with 330g sticks with glass elbows? The RF97a was too light for me…
Anyhow i find it ironic all this talk of light racquets and hurt arms. Nothing protects the arm like a heavier racquet.
Also its not clear if he is talking strung or unstrung weights. Seriously doubt joker is 328g strung.
Also you know most mistakes rec players make is accelerating too fast and light rackets magnify that error.
In my novice opinion weight might help tennis elbow, maybe, not a cure all, if I was to blame equipment instead of technique, I would first look to string type, string tension, and flex, but I'm not sure the video really focuses on tennis elbow, the comments in this thread had a little discussion of it.
