Thank you for the explanation. I thought it might have something to do with construction differences. So you're saying HD Lights won't damage a 114 or 214?
Check out the Elixir site and compare the string gauges of the HD and the Lights: just the G and B are different, that's it! There is nothing "HD" or different in terms of construction about this set. Like
any string choice, it's all about not only the tone of the string, but the tonal
balance across all six strings. So you can personally bias the balance toward the treble side with the HD set, or bias toward the bass side with Medium-lights, or choose between 80/20 or PhosBronze, and even put medium gauge on your GA. Experiment, and then settle with the set that fits your fingers and ears best.
