I want to feel the clubhead more at the top of the backswing

SwingWeight:

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

Shaft flex:

More flexible shaft. Choose shaft with RSSR that is at
least 10-15 mph lower than the actual swing speed of
the player.

Shaft weight/total weight:

Decrease shaft weight and total weight by at least
30-40g and build with a "head-heavy" feel, achieved by
using a swingweight that is at least D3 - D4 based on
men's traditional standard length.

Grip weight:

Decrease the grip weight by at least 10-12g.

Golf club balance point:

Assemble the clubs to a lower balance point by using a
higher swing weight, lighter grip, lighter shaft or longer
length.

Length:

Increase length of woods by at least 1 inch and the
irons by at least 1/2 to 1 inch, only if the player can hit
the ball on-center a high percentage of the time with
the longer lengths.
