Been playing the 913d2 for a while with a diamana ahina72gr stiff shaft in and love it . Was fitted for the 915 but can't seem to find the right shaft tried the aldila rogue 60 and the diamana d+whiteboard 70 but cant seem get on with them feel too stiff compared to my ahina any ideas on shafts to try? Love the 915 head so want to get the shaft Cheers
