re: 2023 non-grand slam tennis thread.

I tried to do a quick dive in some forums. A UK stringer said they strung him at 54, but didn't get into anything about different tensions.

I saw some speculation on other forums it's probably higher tension on return for more control and lower on serve for more pop, but then they had differing info on which racquet has more weight/lead.

ETA, one thing I don't completely understand is swingweight. I get the general concept of head-heavy versus head-light. But, I've read some anecdotal stuff that the real racquet ninjas like Roman Prokes can help a person a ton and really change the feel of a racquet by playing with swingweight.
