Does anyone know whether Titleist tips the Tour AD BB 7 for the 917 driver at all? I'm presently playing the original Diamana Whiteboard 83x from my 910D3 in my current 917D3 and my understanding is that these were tipped a half inch back then. I'd like to try something a little lighter in my 917 and I don't see the original Whiteboard 73 as being an offered option.
