I'm all up for innovation, and this could be in fact a great thing, we won't know until we try it, right?
But to me, it just feels they are selling snake oil, none of their claims makes sense.
"We kept it light due to German manufactured Carbon"
No, you kept it light because you are using a Kiri core, probably some very hollowed handles too. It will probably very head heavy too, but that's a design aspect, not a downside in my point of view. Some people like head heavy blades.
"Bigger hitting area and sweet spot"
Hitting area and sweet spot are not the same thing, and they can even be inversely proportional because a bigger head size causes more lateral and torsional instability. But this also depends on other factors such as shape and composition. So I would love to see some real data on this, not some fancy graphs drawn over the shapes of the blades that tell us nothing. Besides, do we really need a bigger hitting area?
"Linear frequency response"
I like this one very much 🙂 What does this even mean? As Yoass pointed out, the vibration modes of this blade will be much more complicated. Again, I would love to see some real data, not some image of a blade flexing. But what this shape does is to make the blade flexier, more mass vibrating further from the flexing point, and less material to resist the deformation near it. Is this beneficial or detrimental?
