No. Aero throat is made in that shape precisely to achieve highest possible lateral stiffness, for top spin and kick serves for example. Aero VS throat is super stiff in all directions, just like RF97A.
Shift is experimental, and while its lateral give softens the stiff impact it also kills the energy transfer racquet->ball, top spin balls with Shifts aren't very energetic, they are easy to place but slow and noticeably weak. RF97 and RF01 Pro are the exact opposite, it's very obvious how pacey and energetic top spin balls get, difficult for the opponent.
RF97A has a superstiff throat and general lateral stiffness, so does RF01 Pro, measured at 82 and 85 respectively. Aeros are in the sameish ballpark, some stiffer ones especially, like VSes.
I don't remember what were Shifts' values for lateral stiffness, but like 65-70. However, RF01 has a measured lateral stiffness of 70, dramatically lower than RF01 Pro at 85, and it's immediately noticeable in play. RF01 really prefers full flat hitting, is generally a softish but stable frame with a totally different flex profile vs Pro which plays with loopy spins super easily, picks up balls at ankle level with total ease etc. RF01 is still OK with spin, it's torsionally relatively stiff, but as a whole it's a quite different raquet from the Pro
Do you have any recommendations for other stiff throat and general lateral stiffness but lighter racket?
