Each putter's specifications are located on each product's page in the Specifications dropdown. If you need information outside of that, please contact customer support.

Head weights are indicated by markers on the bottom of the putter head, or on the weights. All putter head setups are 340 grams, 355 grams or 370 grams. The proper head weight is determined by the putter's length to ensure swing weight balancing.

Putters that have weight wings, backs, or rings can be adjusted. Older models and classic putters do not feature adjustable head weights. The head weight will not be adjustable for those models.

We use a tape measure from the bottom of the sweet spot to the top of the grip.

Yes, this may require a new shaft/hosel/grip that is built to the proper MidLock specs. Stock specs are 71 lie, 4 deg loft, and about 6 inches longer than your standard length putter. Additional weights may be needed to reach the recommended head weight for MidLock which is 380g.

Putter covers are generally interchangeable for blades and mallets. Any blade head cover should hit a blade putter. The same is true for mallet putters. Some putter types including center shaft and mallet models – Zero, ER8, and ER11 have a unique head shape and have a cover specifically designed for a perfect fit.

High MOI means more stability in the club head when moving through the ball while putting. This will help with limiting the deflection of the head on mishits and making the putter smoother during the backswing.
