Two readers went through Wilson Staff's putter fitting system and found that custom weighting was what they needed.

"Doug has been using the same putter for more than 20 years. As a scratch golfer, he's obviously done very well by it. Sometimes we get lucky and pull the proper equipment off the rack. But Doug was ready to try something new and liked the feel of the mid-mallet KC3."

Know your limits: A putter's head weight can make a big difference in performance and feel. The general consensus is lighter heads are better on fast greens. For slow greens, a nice heavy head will help you give the ball a rap. Of course, you may find the opposite to be true. Which is why putter fitting makes so much sense.

	Grip Weight	Head Weight	Loft	Lie	Length	Head Style

After	Mid-Weight(45-gram plug inside the grip)	Heavy (includes 65-gram brass sole-plates	Standard	Standard	36" *	Toe-Down Mid-Mallet
*Fit for 36" putter, but Wilson doesn't offer it in that length.

Reader: Jean-Louis Lafforgue

Age: 57

Handicap: 16

Occupation:Banker

Old Putter: Toe-weighted mallet, 35 degree, standard loft (4") and lie (72")

New Putter:Wilson Staff KC4, High-MOI large mallet, 35", standard loft (4°)and lie (72°) $199; wilsonstaff.com

Fitter: Hiroshi Okada, Custom Fitting Specialist, New york Golf Center, New York, NY "Jean-Louis was crouched at address and his putter sat too upright. This combo promotes pulls and, sure enough, his misses favor the left side of the hole. I wanted to get Jean-Louis into a face-balanced mallet to maintain squareness at impact as much as possible. The 35-inch KC4 was ideal; it sat perfectly flush to the ground."

Know your limits: The latest generation of high-MOI (moment of inertia) putters work like pendulums back and through the stroke. This helps straighten attempts from long range but, more importantly, reduces misses on those tricky five-footers.
