For me CC is faster and harder. You cannot really trust the freq. readings of a blade alone to judge the speed. both blades also have recorded different frequencies one lower or higher than the other.
I did not see the Mark V. If he has problems controlling Mark V then he needs a slower rubber like a Chinese rubber that is not too tacky. The problem here is technique and level.
I don't feel much difference in speed with the 2 blades but if it is looping and you want the ball to really kick after the bounce, that would be azalea off.
Intensity is the fastest with the least flex. Azaleas have a lesser hollow feeling and are suited near the table. Could be at mid distance with very fast rubbers.
Waldner senso carbon has a somewhat bigger sweetspot due to the carbon layers however back when the ball was at 40mm, the blade was not that fast probably at off speed only and not at off+. It should be a little faster than offensive s.
Let me correct that. Originally it is also SAL bit changed to HAL. The SAL is the blue arylate while the HAL is the orange arylate. I was used to calling it SAL but they mean the same blade.
