Broadly speaking, there are two different types of putting strokes.
Stroke Type 1 – Straight Back Straight Through
Players with this type of stroke are best suited to face-balanced putters. This round-up review highlights an excellent selection of face-balanced putters that are currently available.
Stroke Type 2 – Arc Stroke
This stroke type is better suited to putters with more weight in the toe. Instead of being ‘face balanced’ the toe of the putter will point towards the ground if you balance the putter on a horizontal surface.
