Not having shaft adapters available from Titleist for the 910 series of clubs is an unfortunate marketing decision that should be reconsidered. It deserves input from qualified top professional club fitters who understand the custom market and could promote Titleist clubs in ways that would advance the brand. The current adapter policy has the net effects of sending golfers and professional club fitters into the arms of competing companies. Titleist's arguments for the current policy have little merit and are harmful to the brand.
