If you need help with owning too many, call 1-800-PUTT-ERS if you need someone to talk to. Unfortunately when you call you get a voice message stating that the operators are currently playing golf and won't be back.
It’s good to have an extra putter for a change of pace when your putting gets in a rut. But some of us, me included, go over board I guess. I had 13 at one time but I’m down to 2. I do have my eye on number 3. Lol.
