Spider Mallet is available in two lengths, 38 and 35”. The idea is to grip the club as you would a normal-length putter, with two or three inches of the butt-end of the grip extended above your hands, which gives you the maximum benefit of counterbalancing. Thus, if you normally play a 35” putter you should opt for the 38”; if you play a 33” putter should use the 35”; if you play a 34” putter you can experiment with both the 35 and 38” to find which you prefer.
