915F / H with a steel shaft

hello chap you should be able to upgrade to steel shafts - Nippon work really well as are lighter There may not be a huge price difference if any as generally steel is less expensive than graphite The only issue you may have is the fitting of the adjustment fitment at the end of the club, however your local pro should be able to tell you if its possible I know you can fit steel to non adjustable heads so just not sure about adjustable ones length wise it would be the same as a graphite unless of course your are shorter or taller than average? however I use a 1 inch shorter shaft in my driver and three wood purely for dispersion reduction best bet is to go to your local fitting centre take a look Ian
