Where are you trying clubs as my club had lefty demos? Also have you checked out a Titleist Thursday yet they should have them.

Your site can contact the local Titleist rep or a call to Titleist should be able to arrange to have some there for a date. Other sites and Titleist Thursdays will likely have them. Be sure they get more than just one in. You may not "always" be a 10.5 or 9.5 guy with the 917's. Demo days and advance fitting centers have the large suitcase with the top row being RH and the bottom being LH.
