I realize most people are interested in the lobster meat, thus they purchase the largest size lobster which is affordable. Sure, I love the lobster meat, but since I have osteoporosis, I’m more interested in the shell. I purchase the smallest size available, because the shell to meat ratio is much greater. As a bonus, the smaller sizes are more affordable.
