I be reluctant to compare a box frame with an Aero frame, especially a sword one. I believe what makes this racket relatively fast for a box frame is the 4U weight and it's relatively thin frame cross section (i.e. the face where the grommets come in and out from.). I've played quite a bit with a JS12 and VST is slightly slower, but more solid than that. Then add on the fact that a Jetspeed frame is slower, but more solid than a bravesword one. Note I've also used a BS12L 4U and BS11, but not as much as a JS12.
Decided to buy mizuno vs tour. My 1st mizuno racquet.yaayy. I’ll try comparing it with my trusty 4U BS12. Another collection to add in the bag along with my n7,BS12,Bs12L,Arc11.
