I'm about to hit level 79 and am contemplating upgrading my G10 irons to the Burner 2.0s. From what I gather, the Burners are a worthwhile upgrade. However, I have noticed that most of the people saying so are playing with very high level balls with quite a bit of feel. For the time being, I don't plan on paying more for balls than the GI-SD. With that in mind, am I better off sticking with my G10s until I upgrade my ball type, or is the meter speed increase offset by the other club attributes even with the GI-SD?
