Just received my new (to me) Bridgestone J38 driver with Fujikura Motore F1 65 s shaft. I think I am in love. My old driver was a Macgregor v-foil eye-o-matic M38 that came as a package deal with the bag I bought off craigslist for $45. Needless to say, this is a huge upgrade for me. I haven't quite been to the course yet but after a couple range sessions, it looks like my mis-hits now go about as far as my old clean hits. And my clean hits, I think have added a good 30 yds.
