Can someone suggest an equivalent lightweight shaft for new vokey sm4 wedges? I have TT Dynalite Gold SL R300 shafts in my miz irons and would like something with equivalent characteristics in my wedges. I currently have miz TP-10 wedges but the shafts feel too heavy. They are Dynamic Gold wedge flex (which I believe have the same or similar characteristics to a Dynamic Gold S200). I'm told the Dynalite Gold SL R300 is not a Titleist option in the UK despite it appearing on all their literature as a custom shaft.
