I was in the same situation, and when I returned to my golf pro he tweaked my swing and i hit my driver good. I later went out and thought i could buy a couple more yards but it turns out I lost yards switching shafts. I am currently back to my old shaft (Pro Launch Blue) and am hitting the ball good again.

If you do go and get a new driver I would suggest the G2-G5 or G10 when it comes out in the fall. PING makes very good clubs. I hit my G5 about 40 yards farther then my Taylormade Burner. The G5 is forgiving. while you want to fix your slice, you might want to go with the taylormade R7 Quad or SuperQuad which offers a draw setting, also a Offset driver will fix or reduce a slice/fade. Offsets are normally found in higher degree's (10.5, 13.5) which Ping does offer.
