I was fit for the same club but turned down to 20.25 and +1/2 inch. Definitely goes high and sits soft. It would be a 3 iron/3 hybrid replacement for me.
I haven’t trusted the fitting enough to order it. In a previous fitting I was fit to same setup but with 1k Black 85-S. I haven’t fallen in love with the feel of GT2 so I’ve bought a G440 Max 7W off BST (I play a G430 Max 3w). GT2 will be a backup plan for me if I don’t like the G440.
