Good evening, I have found a lot of info on the score shaft in the paks, but am struggling to find many reviews of the pak graphite offerings.  Most of what I have found says MPF PRO + plays up 1 flex.

I have a max 91 mph 7i speed and prefer it around 86 to feel in control of the swing and not lose myself.

I was fit locally into Modus 120s +1/2  easy enough, they felt nice and produced good numbers.  Modus 115, I really dont like how it feels compared to the 120s.

With issues in my elbow and wrist it was suggested I try graphite. Also want to try Maltby- so this is easy enough Maltby graphite are about +1/2- awesome but this “flex up” for the mpf shafts confuses me.   Should I be getting a regular shaft?

I realize I probably lose some penetration and gain height but considering most of my irons are lower flying, Im not completely against it.

I know its not as simple as Im trying to make it and I know the weight will be different but thats part of what I am looking for.  If the Gabe guy can game the score shafts, I know I can too but hoping for some direction on the MPF + graphite iron shafts.  Thanks
