Hit sand shots less thin

I want to hit my sand shots less thin

SwingWeight:

Increase by at least 6 points or try to increase the
swingweight of the SW to be at least 6-7 points higher
than the Nos. 1- through 9-irons.

Total weight/shaft weight:

Lower the total weight at the same time the
swingweight is increased to make the clubhead more
noticeable.

Grip size:

Disregard the fingertip to heel of hand distance as a
sizing factor and increase the grip size to make it feel
more comfortable.

Grip weight:

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

Golf club balance point:

Assemble the SW to have a lower balance point by
using a higher swingweight, lighter grip, lighter shaft or
longer length.

Sole angle/sole radius:

Use a bounce sole angle from 8-12 degrees in the SW
and never allow an excessive bounce sole angle of
greater than 15 degrees. Use a more narrow sole (less
than 3./4 inch) with less front-to-back radius.
