I'm thinking of having my Newport sent to the custom shop when the golf season ends. Of those of you who have done this, do you recommend getting the authentication done? I'm basically sending it there for some engraving, paint fill, add a sight dot, and a stamp.

Is there any benefit to having this authentication done besides proving that it is in fact real if you were to sell the putter? I'm planning on gaming this thing and don't collect putters.

What do you think? It's $65..
