THANKS Lloyd.
As an indulger of all that is needlessly complicated, I'm not against extensive modeling before cutting.

D Amos already pointed out how the dynamics are effected.
You could model mat'l removal in 2" increments for fun. Maybe find a swing effort or MOI that suited you. or not. Lots of cg fun right there. And nothing but pencil lead on the shop floor.

Implementing is then a whole 'nother thing though.

Out there doing it best I can.
