I would suggest finding a fitter who can place you in the best Titleist head and shaft combination for your swing.

That way you eliminate any guesswork, and get a club that should give you great results for many seasons.

To add to Robert's excellent suggestion, do not give up once you make the transition. If you have been swinging a Burner, you have been comfortable with it for a very long time. That could make the move to such a dramatic difference feel pretty awkward for a while but after a while, you should see significant gains and increased confidence in the newer technology.

I am living testament that getting fit is the way to go. I was hesitant at first cause i thought my swing wasn't good enough for fitting and that it would just be a waste of money. So i usually do the free in-store fitting which is okay but not as comprehensive if you pay and get fitted by an authorized titleist fitter. Mine cost $40 and it was the best $40 i've spent in my life. Got extra 25-30 yards with an 8 deg TSR3 HZDUS CB shaft.
