What is the stiffest shaft 4U HH racket i can buy online?

Super stiff rackets are usually highend rackets and don’t really sit within the lower or mid price ranges,at least this goes for the big 3 brands.

Other options could be LN’s Tectonic 9 or Victor’s (original) Ryugua. But both also rather expensive.

Or look for Forza rackets. Some of these are really stiff too and should be cheaper than the big 3.
