Read driver head CG to predict launch and spin
The fitter explains Titleist's GT driver heads by where the center of mass sits. The GT1 is the furthest perimeter-weighted head, so it launches highest and spins most, while the GT4 is the furthest forward-weighted head, so it launches lowest and spins least. Knowing where mass sits in a driver head predicts its launch and spin behavior.
