I disagree. If your ball hits the grooves a certain way i guarantee your ball will be affected with spin. Look at irons for example.

Drivers that have grooves all the way across, do impart a small amount of spin on their own, but not much. The ones like the BBs for instance, that don't have the grooves all the way across, don't make a huge difference. The real spin comes from the face angle, the launch angle, and how you strike it. Possibly wind conditions too.

grooveless or illegal lol ? your ball has alot to do with spin also

Grooveless. My driver is legal..although it shouldn't be..it just works too good sometimes..Yeah, the ball definently makes a difference too. I guess this being illegal, is more of a case of better safe, than sorry. Why take the risk of someone maybe having a small advantage over everyone else?

That's not exactly a great example..the difference between irons, and drivers are profound! Drivers have very little loft, and irons have a lot, because they are intended to be spun a lot more, than the woods are. But, you are also right that the grooves do have an effect, although miniscule on it's own. It's other factors, coupled together with the grooves, that determine the spin rate the ball will have.

Look at the results from the many tests that have been run over the years. The USGA has run tests with identical irons except for the grooves. They have tested with square grooves, V grooves, and with no grooves at all. The only time that grooves make a significant difference is from the rough, and then the only real effect that the grooves have is to channel moisture and some of the grass away from the contact point. From tight lies in the fairway, the grooves do not impart significantly more spin than the smooth faced iron. This is documented fact, tested and confirmed.

If the grooves were what created spin in woods, then nobody would ever hit a slice or a hook, because they don't put vertical grooves on the clubface. The ball would always just slide off the face and never get any sidespin applied. However, we all know that isn't the case. So if the driver can impart sidespin without vertical grooves, why can't it also impart backspin without help from a horizontally grooved face?
