Hello,

I have just got Diamana Blue shafts from my friend. He took them off from 909H and 909F. My question is whether it is possible to use these shafts on my 585H (21*), and 906F2 (15*) or 906F4 (18.5*), respectively. I understand that this might change the shafts' stiffness, but for now I only wonder about the physical possibility. 

Looks like the length of the shafts will have to be shorter, right?

Thanks in advance
