Bio Cell and I got off to a slow start today (major swing issues) but we warmed up to each other and tore apart the back 9. I find it doesn't matter whether I hit it high or low on the face, left or right on the circle of the face..I see the same flight. It's just one big sweet spot.
Massively forgiving face on this one.
While the Bertha is getting a lot of love, I think the Bio Cell takes the cake for best driver I have hit this year.
