Typhoon Would it hurt to take your current driver and go to a store with a launch monitor and have them help you out. Grab a Ping, Cobra and Taylormade. Hit them all alongside your own driver. Dont pay attention to the distance foe each club since the monitor could be weird. Look at how each one compares to the baseline set by your current driver.
Spend a bit more, get a decent driver...plus you'll be able to see the comparision there in the store. Dont waste more money on a Big Bang with a shaft thats a guess.
First issue, no sim within a 100 miles.
Second, I owned a Big Bang and know how it plays. I have also been building my own clubs for 15 years and I have a bunch of shafts that I know fit me that I can try in it.
