Tiger should switch to a Nike putter and strike a deal with Nike that they will produce an unlimited retail "replica" version of his Nike putter with all the profits of that putter going to Tiger. The TW putter could be purchased in different length, different weights, with or without site dot, site line, etc.
It would generate big sales for Nike's Method and other putters and it would generate big income for Tiger while boosting his ego, adding a putter to his other personalized Nike gear in the TW marketing machine.
