I recently purchased a 913 d2 driver from American golf and was less than impressed with the fitting service I received, especially seeing as I paid the full price!
i took my driver to Tavistock golf club and spent some time with the pro there Glenn Richards and I can not praise the service I received enough, so much so that I amended the whole set up of my 910 woods and fairways.
glenn spent 4 sessions with me each about an hour long and let me demo equipment and shafts to my hearts content and never once rushed me or tried to push a sale.
i just wanted to recommend visiting an independent retailer over a corporate brand like American golf the service you receive is a million times better.
cheers
