Another thing to note. Frame profile is..interesting IMO and they dropped shark tec from this piece too.
Btw, I've just recently discovered Gosen Gungnir and especially Customedge Ver. 2 series. They are incredibly aerodynamic... cuts thru the air even faster than BS series. Check them out if you get a chance.
I have but can't share the same opinion. It's probably because of the balance that makes it go faster more than just the aerodynamics of the gugnir as they share the octablade frame with the MXs which are OEM by fleet. As for the customedges. I've not paid attention to them because the Mizuno JPXs are far more promising to me in terms of speed as they've adopted the sword frame on those.
Spec is one thing, but feel is just as important. If it's as good as BS12 in terms of feel, it'll be on my try list!
You're saying it's stiffer than BS12? If so, how can that be a successor to the legendary racquet? When will the racquet be released?
Just imagine js12 as "the not so stiff js10", it will be easier like that than comparing directly to bs12. I sometimes imagined if only js10 not so stiff so it can pack more power in exchange with its shot accuracy, it will be my dream racket. The aerosword works better for me than the sword frame technology because it gives my shot more power. I will definitely get the 3u ver. Of js12 when it is already released. Some says the release time is around august.
