Hit ball more solid

I want to hit the ball more solidly (on-center more of the
time)

Length:

Decrease length of the woods at least 1 inch. Decrease
the length of the iron by 1/2 to 1 inch.

SwingWeight:

Increase by at least 3 points and do not allow to fall
lower than DO (based on men's traditional standard
length).

Shaft weight/total weight:

Match to tempo of player starting with lower total
weight but with normal to slightly higher than normal
swingweight. If this fails, increase the total weight
without allowing the swingweight to fall below normal
levels.

Grip size:

Increase to make the grip feel more comfortable and
disregard the fingertip to heel of hand distance as a
sizing factor.

Clubhead design:

Match the clubhead size to the desire of the player. In
many cases a larger head shape can help by increasing
confidence.

When contact is on-center but does not feel solid

Shaft flex:

More flexible shaft. Choose shaft with RSSR that is
equal to, or lower than the actual swing speed of the
player by 10mph.

Shaft bend point

Choose a shaft with a lower bend point.

Clubhead design:

Center of gravity
Make sure clubhead design of choice has the CG
located in the center of the face scoring area. Make
sure the CG is not too high.
(see CG Estimating Chart at foot of page)

Loft:

Increase loft by at least 2 degrees but only if the
golfer's need for more solid feel outweighs the
possible distance loss.
