Personally I still haven't come across an E-string that would still feel right dropped to D without being too stiff when tuned to E. If I really have to use drop D I'd have another bass with an appropriately heavier string for the low D. (This is what I do with my guitars where I use a 52 for E and a 56 for drop D.)

I will play devils advocate and go against my own earlier post and say that in some cases, mainly the ones discussed in this thread part of the point is the timbre of the flappy E string, your idea of the bass playing as it should when tuned to D by the use of a different gauge string would defeat the object of the whole sound some people are going for, these songs were and are still being written on a detuned E string rather than a state of the art bass strung specially for two numbers at a gig requiring multiple basses to be taken too, would you 4 string pioneers agree with that?
I have never found a song requiring the need to drop my E on a five string yet and the times it is easier on five far out weigh the reverse, I am not pointing the finger at anyone here as I think most of you look like you understand but some people cant get there head around the notes that are far away when in drop D will not be so far when playing a 5 with correct positional fingering because we still have the E where it should be so the original notes fall to hand, where anyone tries to think of really tricky songs to catch us out they forget we can go across as you would on a B strung 4 string or up as you would on an standard tuned 4 string.
