Own several putters of different styles.  Change between them whenever you lose confidence in the one you used yesterday.

The Maltby HT1.  A line of aluminum/brass putters with very high MOI, in three conventional blade and mallet-style designs.  About $65.


The Golfsmith Snake Eyes putter.  A bit of a copy-cat design, but still well done and well-designed.  About $70

Snake Eye's Strike Line putters more the mass to the ends and rearward for higher MOI.  A nicely done and handsome putter design. $70.

- putters can be built for as little as $15... if you don't care about making putts. A properly engineered and fitted putter is a joy to play with, and will run you between $40 and $80.

Moment of Inertia- MOI is the buzzword in putter design these days. Even a mid-handicap golfer will typically miss the sweet spot on his/her putter face by about 1/4".  This will twist the club head and the putt will miss its target line. Higher MOI means less twist, and therefore, less miss. 

There is only one right Moment of Inertia for a putter head design... as much as possible. Compared to evenly distributed weight, high MOI increases the effective size of the hole by a factor of almost two.  Therefore, your putter head should be as light as possible in the middle and face of its body, and as heavy as possible in the ends and rear.

Almost all putters now come with 4 degrees loft cut into the face. It provides just the right amount of backspin and skidding in the ball, while avoiding driving it into the ground or lofting and bouncing it. But you want 4 degrees effective loft at impact, and your grip, stance, and putting swing change the effective loft.  Ideally, you would correct any defects in your setup or/and swing, but I can also adjust the putter itself to give you the perfect loft.

Lie Angle - Lie angle is critical to long putts.  If your club does not rest parallel to the ground, the mere 4 degree loft of the club face can push the ball a fraction of a degree left or right of the center of the cup, enough for a close miss on a long putt and a lip-out on a mid-length putt!  The effect is even worse if you hit just a smidge off center. You have to have a consistent stance, and your putter's lie angle has to be adjusted (bent) so that your stance puts your putter head square to the ground.

Length- Belly-length, chin length, knee length.  Whatever works for you.  While the length of a putter is its most obvious characteristic, its the head design that puts the ball in the cup.  But if an unconventional length works for you, we can build it.

Shaft- The shaft material is not a critical element of a putter.  Any good quality shaft is good.

Putter Grip- Technically, any putter grip is as good as the next one.  But its a question of feel, which is a critical element of good putting.  There are hundreds of grips for putters on the market, and none of them are expensive, so take the time to find some that you like.

Maltby's Xtreme series goes to the extreme to get the MOI out and back.  Together the super-long blade and the odd-looking mallet offer the highest off-center hit correction I have found. Around $80.
