This post actually adds to the confusion.do not confuse stiffness with solid feel. stiff woods by default cannot have a soft feeling
for example primorac blade korbel and stiga clipper all have limba and ayous
but the softer feel is to primorac blade which has the more flex and vibration also, korbel in the middle an stiga clipper is the stiffest/harderst and fastest of all blades
Stiff blades can feel soft, Clipper is an excellent example.
Primorac is just about as soft, but is thin and flexible.
Don't mistake the flexibility for softness, (or stiffness for hardness) it's not the same property.
The stiff construction is what makes Clipper fast, not the material hardness.
