D'Addario's here too... for lower tuned 6 strings, i tend to use a pack of 7s and take out the middle (.24 i think) string, else it'll just be a set of 9s. I did have an 8 on the top a few times, and i really liked that, so i might pick up a few singles and make something like 8-46. The 8 did seem to snap easier, but i think that might have been down to technique of always playing on 9s.
