Just received and read the latest edition of Sports Illustrated.  Was exceptionally pleased with the article on G9 and G10 on the 15 year history of the Pro V1.  The stats used to accompany the article are very interesting, especially those on market share in January 2015 and the number of starts for worldwide tour pros in competition between Oct 200 and the end of 2014.  Kudos to SI for the article--and to Titleist for making the best golf ball in the business.
