I recently got fit for a new 915D3 9.5 degree driver.  I really like it and the 9.5 in the A1 hosel setting gave the best launch/spin combination.  I live in Texas and play hard turf courses so I really like the runout I get with this driver.  However, my launch angle with this club is lower than "ideal" and I may like a higher trajectory and more carry when playing softer turf conditions.  I am curious about the differences between the hosel settings and a higher loft driver.  Should I expect the same measurements with my driver in a D4 hosel setting as i would get with the 10.5 degree version of the driver set up at the A1 setting?  Or, do I get to buy another driver?  :)

Thanks,
