A buddy also has two that are right around 310g. It seems to me that 315 is the max weight that the Ki5 can have and they really shoot for 310 +/- a few grams. The Ki5 is pretty popular at my club and they all play the same, so maybe even if they are off a few grams they still play identically. It bothered me at first, but now I don't care since my elbow has healed while still being able to play aggressive tennis.
