I recently picked up a 54* & 58* T20. Ordered through AG. I asked for DG tour issue S400 shafts. When they arrived the shaft label had DG wedge flex. Not the tour issue label expected. On the order sheet it also states DG Wedge Flex. Looking on a Mizuno website it would appear that these are in fact two different shafts. Does anybody know what DG wedge flex is? S300? S400? When I asked AG about this they told me I had the Tour Issue S400 but I don’t believe them. Since they’re custom and I’ve used them I can’t return. Is there much difference between the two shafts?Thanks in advance
