I recently changed my shaft in my 913 D2 Titleist Driver  from the Titleist Barrosa Stiff Flex to the Diamana  Reg Flex...My question to you is:  One of my friends wants the Titleist  Barrosa stiff Flex shaft....what type of Titleist  Driver will the adaptor fit..913? and what other driver heads.   Also I had the Same shafts in my 17 degree and 21 degree Titleist 910 H Hybrid clubs...what  hybrids  will these shafts with the Surefit Titleist Tour hosel fit...numbers for the hybrid heads???  Thank  You
