I'm in the market for the new 716mb's and would love to get the Nippon Modus Tour 125 shaft. I don't see them in the custom book and when I called a retailer they said they were not an option, although reading through Team Titleist posts on the same subject I read as of March 2016 that they are available. Would like some clarification before I order my next set of Titleist blades. Thanks
