I guess I'm lucky. I've got three BLX 2010 and they all weight 348 with a OG and a dampener. The 2012 I have weights 356.
It really helps to put a 18 gauge string in these racquets. For example, you can lower the weight as much as 7-8 grams just by switching from a 16 gauge poly to a 18 gauge multi (RIP control being the lightest). You also gain more headlightness and maneuverability.
