It's the ball Bill. Clubhead design does not make the ball go straighter.

I dunno, Garland, those big headed drivers are sure a lot more likely to turn an off center hit into a straight ball than my old persimmon head Hogan driver. Anything outside the dime-sized sweet spot of that sucker left the tee spinning wildly. The gear effect was offset by the sidespin.
With the new drivers, although I still don't like any as big as the 460cc jobs, off center hits go much straighter. I don't think it could be from the ball.
And what's this Wishon guy know, anyway?
