I want to stop pushing the ball

Face angle:

1 degree more closed than the previous face angle for
each 5-7 yards of push to be corrected.
Lie (particularly in the middle and short irons)
Lie should be fit in one of two dynamic fitting methods
to be correct for the golfer.

SwingWeight:

At least a 2-point decrease if swingweight of previous
clubs is believed too high for the strength of the player.

Shaft weight/total weight:

If previous clubs are believed too heavy in total weight
for the player, decrease shaft weight by at least 30-40g.

Lie:

Lie should be fit in one of two dynamic fitting methods
to be correct for the golfer. If the golfer pushes the ball,
look to make the clubs more upright, especially in the
middle and short irons where greater loft magnifies the
push problem for each degree the clubs are too flat for
the player.                                            

Grip size:

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

Shaft flex:

More flexible. Choose shaft with RSSR equal to, but no
more than 20mph lower than the golfer's swing speed.

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).

Clubhead design:

Weight distribution
More heel weighting in the woods. More perimeter
weighting overall.
