Hit ball straighter, stop slicing the ball

I want to stop slicing the ball

Face angle:

1 degree more hooked than the previous face angle for
each 5-7 yards of slice to be corrected.

SwingWeight:

At least a 3-point decrease if previous clubs are above
D4 (based on men's traditional length). It is also
possible for a slice to come from a swingweight that is
way too low for the golfer, in which case the
swingweight should be increased by at least 3-5 points.

Shaft weight/total weight:

If previous clubs are very light in total weight, try
increasing swingweight at least 3-5 points before
increasing total weight. If swingweight is already at
normal to high level, increase shaft weight by at least
30-40g. It is also possible for the slice to come from a
club in which the total weight is too high.

Horizontal bulge:

Less bulge (flatter face) if the golfer hits the ball off the
toe of the woods regularly and the current woods have
excessive bulge (inches of radius less than 8 inches).

Length:

Shorten by at least 1 inch

Shaft flex:

More flexible shaft. Choose shaft with RSSR as much
as 20mph below and never higher than the golfer's
swing speed.

Lie:

Lie should be fit in one of the two dynamic fitting
methods to be correct for the golfer. In some cases, the
lie could be made at least 2-3 degrees more upright
than
proper for the golfer in the woods to help correct a
slice.

Grip size:

Grip size should be comfortable for the golfer
regardless of the distance from fingertips to the heel of
the hand.

Clubhead design:

Weight Distribution
More heel weighting in the woods and perimeter
weighting overall.
