I recently went to a Titleist demo day and hit a 910 D3 with an Oban Devotion 6 shaft. I was wondering which flex do you all typically carry at your demo days. Is it usually a O4 Flex or an O5 Flex? I think it was an O5 but I'm not 100% sure. I was hitting it up against a Diamana 'ahina X-stiff, so that also makes me think it was an O5 flex, but I would love a reassuring answer. Thanks.
