Regarding the club head, it is composed on new titanium clubs. This material provides comfort and tolerance power. Indeed using a titanium head, the shaft will be lengthened. Thus the force be larger and thus speed the club faster and your ball longer. Tolerance does not mean control effect on a ball a little decentered titanium allow a good tolerance for error.
If you have any regularity and you begin to touch the ball much prefer a steel head that will allow better of you better be able to work the ball as well as the control.
Regarding the shaft must be adapted to any club at the speed of swing. Generally graphite, the rigidity of the latter varies. It is a mistake to think that rigidity = power in very few players should play with stiff and it is not uncommon to see people play which is a shame they lose their level.
The club is facing steel very hard to see titanium. The latter is fine and is used to redistribute weight around the latter to increase the striking surface and thereby increase the tolerance of beatings eccentric. It also increases the coefficient of restitution (COR) for more distance. That is what we call face trampoline.

Prefer to Driver 3-wood!!

More head volume is more important it offers comfort and tolerance. But that will not want more power. Big head does not mean especially big length.

The connection between the head and shaft is called hosel are made “through bore” that the shaft enters the club head thus gaining power and stability.

When at the opening of the club face should vary depending on the speed of swing. Indeed it is inconsistent to play a stiff Driver in 13 ° aperture. Plus speed, the lower the angle to take off is important to carry the ball as far as possible. In an Driver too close for a slow swing would be far less a 3-wood.
The wood or driver angles were closed for more distance in order to have a fast swing.

Attention often leave a driver is a reflex but the difference in tolerance between driver and 3-wood is so great that it is better to play a wood three for intermediate players a driver.
