If you know your EXACT shaft profile as opposed to one you're relatively happy with, are you going to get the ultimate custom fit one off profile manufactured in steel or graphite given that (and I'm guessing here) steel will be considerably more expensive. I'm thinking along the lines of one off profiling being the next stage in true custom fitting and graphite is the only way you can keep the costs feasible going forward. Just a thought, is anyone out there producing Boron iron shafts ala Diamana Stinger? Would be an exciting experiment if you could stomache the cost. By the way anyone still using a steel shaft in their driver (or even fairway metal)?
