I currently have a Fly-Z+ playing at 45.5″ with a Matrix Ozik White Tie 55X4 shaft, the swing weight is D3.

If I install a UST Mamiya Competion 65 shaft, tipped 1″ for stiff flex and overall playing length of 44.25, what will the swing weight be?

I know the Matrix is 59g and the UST is 67g.  I’d like to keep the swing weight around D2 / D3.  So I’m wondering if it’s below D2, if buying a heavier head weight would get it back to D2/D3.  I see they go up to 17grams for the head weights.
