When looking closer at the specs they are equal to the TB ALC though I can't see the dimensions of the handle.
Just to summerize they both have:
Vibration Property: 10.3
Reaction Property: 11.8
Thickness: 5.8mm
Head size: 157x150
Now we just need to know the composition...
Unless Butterfly suprises us, the composition will be the same as the TBalc/TBS/Viscaria/Zhang Jike/Zhang Jike alc
One more blade to the viscaria-like familly.
I still hope another top ply, limba or hinoki........butterfly doesn't produce anymore the Maze (it was a TBS with limba outer) and has never made a TBS with Hinoki outer.
Unfortunately, it really looks like koto again.
