Wow, just made the switch to a Titleist GT4 8 degree 65g xstiff driver and I've unlocked a lot of distance. I went from a Paradigm that I was fitted into, but after two driver heads breaking on me Callaway sent me the Ai Smoke and I wasn't getting the results I initially had. On a whim, decided to pull up to PGA Superstore and after a few different heads found the sweet spot.
