The 2007 Burner was great. I really loved the R9 460 as well. Going farther back the KZG PFT 300 was the first driver I truly loved.
One guy I play with will not give up his G10 driver. All the rest of his clubs (excluding putter) are 1-2 years old tops. He has been trying drivers every year for the last 5 years, but never likes any. He texted Sunday that he demoed the G425 and it's a "maybe", but I am not holding my breath. The driver and putter are his best performing clubs so maybe he is wise not to change.
