There's a pair of 6.1 95s 28 inches in Argentina.
A true mid should not be more than 93".
Raquet finder was my first attempt... it drew up nothing.
...So far it looks like pro stocks and the rare i.prestige mid xl.
And I think you can extend many[?] Head racquets because they use removable pallets and you can just slide them down the hairpin. One of my Prestiges is 27.2" but I don't think you could go past 27.5" or the pallet may crumble.
And there's another one of those in Rome...
Yes, you can extend any head racquet pretty easily. Just replace the pallet 1" below and fill the gap with something solid.
