Beginner putters should be predictable above all else – low speed so they fly as designed at any arm speed, and little to no turn or fade to correct for. These three are all speed 2, stable to lightly overstable.
Dead straight with zero turn or fade – the simplest possible flight to learn from as a first putter.
A touch more glide and fade than the Aviar for a slightly firmer finish, one of the most widely used putters at every skill level.
Similar profile to the Judge with slightly less glide, a comfortable, predictable putter for approach shots and the circle.
