I would doubt you could do it by weight. Bottle quality varies a lot between suppliers. Take a look sometime at the bottles you've broken. Some are nicely symmetrical, with even wall thicknesses all the way around. Others are not, with big differences in wall thickness from one point to another. Those asymmetrical bottles weigh the same as the better ones, but clearly they won't have the same pressure capabilities. There are some breweries out there whose bottles I never reuse anymore.
