How would that not matter? Smaller bearings mean a shorter service life if I'm not mistaken. I'm really not interested in anything else when it comes to BBs. I installed the cups before I weighed them because I'm stupid and impatient but I do remember they felt noticeably lighter than the 7900 BB they replaced.
