Looking to add a 913H to my bag

I just bought a 913 d2 driver with the blue stock Diamana shaft ( stiff flex) and  I went through the fitting process. If I purcahse the 913H should I go through this process again or would the blue diamana be a good fit as well?

Definitely get fit, I got fitted for my 913H, and 913F together, for me the blue diamana was too light on the 913h, so I would tend to hit that inconsistently as opposed to the heavier diamana black 82g.  I was getting less side spin on the heavier shaft and consistent contact.  With my 913f, I ended up with the diamana blue along with my 913d3..
