I’m in search of graphite iron shafts (preferably taper tip) with a bit of bias towards the back end.  I’ll be using some Mizuno JPX825 Pro heads that are from Mizuno’s heavy head stock, and I need to build these +1/2″.

I’d like to find a shaft that can help me get to a swing weight that doesn’t approach Thor’s Hammer.  I don’t mind D3, but anything heavier becomes uncomfortable in a hurry.

Thanks in advance for any assistance you can offer.
