This happened on the 2nd hole today in mid swing? This is an Evenflow Black 65 5.5 flex shaft in a G425 MAX. I bought the shaft last fall to originally use in my G410. I have on occasion hit a fat driver while working on my swing at the range but I've never had a shaft break right at the handle before. I heard it crack and buckle on my downswing tonight. I still hit the center of the fairway though.
