Shouldn't soft blades be faster? |

Here is how I see it, hard blades are tight springs and soft blades are elastic. More elasticity, greater acceleration, "springy feeling", hence, better speed.
Btw, don't they have it all too, less weight, more touch, if thick enough-less vibration, better spin, etc. A good example would be Joola R1, made up of soft plies: Limba and Balsa Core, light weight, one of the fastest in the market, and spinny claimed by users. Not trying to advertise as I myself havn't used it but would it be a good choice? Thx. |

i am not a fan of overly light blades i like blades in the 85g range.
and the soft and slow hard and fast is kinda decieving i think.
hard blades are faster with less effort soft blades are faster with more effort.
think of a trampoline if yo make small jumps you dont bounce that high but if you jump hiigher you go higher.
but if you bounced a baskertball as hard as you could on a tramp it really dosent go that high but bounce it on a hard wood basketball floor and it can go all the way to the ceiling. that is the difference.

i don't quite agree with this... think of the concrete object we have on this case: a ping pong ball. if you hit it against the wall, it comes back at you almost with the same pace, right? on the other hand, if you hit a ping pong ball against a flexible surface, like a trampoline, it's pace is significantly reduced, because the flexible surface absorbs some of the energy the ball carried. the main difference is that the more flexible the surface is, the more it cushions the incoming ball, and therefore the more it absorbs energy. even though the motion of the trampoline getting back to its inicial streched position, this can never compensate the amount of energy that is lost by the cushioning. |

NAh, fella's you have to look at it like this.
Every bit of energy must be used somewhere along the line, A soft blade will absorb some energy, thus less energy is released back into the ball. A hard bat will absorb less energy, therfore leaving more energy to be released back into the ball. Energy In, Energy out. Same with the sponges, Hard sponges dont absorb mush energy, therefore a faster ball is projected, softer sponge = energy absorbed -> slower ball. Try the example hit a ball with just the wood, see how much faster it is, Thats because their is no sponge to take away energy. Of course, with our arm movements we put back energy into the ball, and the rubber and sponge combinations add to this energy. Like a trampoline effect, the faster you hit the ball the more trampoline effect. |

and it is the tramp effect that could make a soft blade fast. possibly

My Kokutaku is the softest amongst my blades, yet it is the fastest.

For some reason, I find that it's easier to kill backspin with softer blades. It's easier to kill topspin with harder blades.

Should we not be talking about flexi vs stiff blades?
Hard and soft are about feel. e.g. Balsa is Soft but it is not flexible. |

"Try the example hit a ball with just the wood, see how much faster it is,

Not only hardness matters but also what is technically called as elasticity (stress/strain). Hard rubber/sponges (elastomers) undergo elastic deformation and retuns all the energy that deformed it.
But not hard wood. since at the point of impact it will have a microscopic plastic deformartion ... causing energy dissipation.
another simple way to verify is that the sound produced by impact with wood is just a part of that dissipated energy. more sound in wood than in hard sponge.
