The stock shaft in the Burner Superfast 2.0 was listed as a mid 40 gram weight shaft. Knowing that you hit the steel shafted driver straighter tells me that a heavier shaft then 40 grams would be a good choice. I would suggest looking at shafts in the 60 gram weight range. The Project X graphite shaft in a 6.0 flex is in between an S and X flex, but it still maybe a good choice. A shaft like the Grafalloy ProLaunch Red Supercharged (TT0110) in an X flex comes to mind. It is also a high balance point shaft which can help to keep the swingweight from getting quite so heavy. It is a shaft designed for a lower launch angle. A shaft like the Mitsubishi Kuro Kage Black HBP 2nd Gen (MR0044) in an X flex could be another good choice. The Xcaliber Pro T6+ (AS0044) could also be a good choice.
At these links scroll down the page to the specification boxes and you can see the specifications for these shafts.
The Burner Superfast 2.0 driver used a .350" tip diameter shaft so you will need to shim a .335" tip diameter shaft to fit the .350" hosel bore. You can use the BB9008 adaptor .335" size for this driver.
