I think one premise to the question is wrong. I do not believe any one "does not have the power" to adequately use the harder sponge. I think many "do not have the technique" to appropriately use certain equipment combinations.
I also agree with the blade stiffness/flex and hard/soft are different attributes of a blade. Lastly we talk about sponge hardness, but it really is sponge and topsheet hardness that matter. We never compress one without the other. Fun discussion.

The buckling could reduce the contact area when the deformation transforms from a disk shape to a ring shape as the velocity increases.
When ONE independent variable is changed, MULTIPLE dependent variables could get affected, and the relationships do not necessarily have to be linear. The assumptions we FEEL to be TRUE and INTUITVE may in fact be non-physical. At this point, we just don't have enough data to tell how deformation distributes among the ball, rubber, and blade during an impact for different rubbers of different hardness and thickness etc. We can't even tell if "topsheet spin" and "mechanical spin" are how tacky and grippy rubbers actually work, respectively. |

Viscaria FL - 91g
+ Neo H3 2.15 Blk - 44.5g(55.3g uncut bare) + Hexer HD 2.1 Red - 49.3g(68.5g 〃 〃) = 184.8g |

so with the above stmts, a lot of the dynamics of the rubber is still unknown to us, and although it is fun to have all kinds of discussions, we should still trust what equipment works best for us (in reality)
