I'm buying a 5 string bass but Elixr doesn't sell packs for 5 strings. So my question is, I'll probably get the Elixr mediums (45-65-85-105 guage) and was wondering which guage, .125 or .130 would be better for my 5th. Lights use a .100 guage, and mediums and heavys use the .105, so I'm !@#$%^&*uming the .130 would be best, but I doubt there's too much of a difference.
