brownmoose13 I think the cog is center of gravity but what is the v?
I think what DonM said about .700 VCOG is right on.....
A big part of the MPF is that the Vertical Center of gravity should be lower than the center of gravity of
the golf ball. If a golf ball is 1.68" in diameter, that means the "equator" of the ball is .84". So, any iron that
has a VCOG less than .84 should be easier to get up in the air, esp. for a slow swinger.
