Question: what is the difference between 16 and 16l tennis string?
Answer: An “L” after a number means the string is on the thinner end of that range; for instance, 16L is slightly thinner than a 16-gauge string. Tennis strings range from 15L to 19, but 16 and 17 are the most popular. ... Strings with more fibers tend to feel softer, and they also tend to be less durable.
