Hi David,  They can use the same shaft, but the fairway would not only be shorter in length, but it is tipped 1" vs the driver, which we would tip 1/2".

Thanks Cathi, what would be the difference in the shaft behavior if I used a shaft that was tipped at 1/2" on a fairway wood?

Since the shaft adaptor is different for a 3 wood vs the driver, they would have to take the adaptor off anyway, so tipping an additional 1/2" should not be a problem.  If you left it untipped, it would just play slightly softer.  If the driver shaft has a 910 or 913 adaptor that was installed and built by us, we offer a retipping service and can put the fairway tip on it.  The price for cutting the shaft, tipping for a fairway, install a stock grip and a new adaptor is $62.00 MSRP.
