Keith,

I'm a bit late to this thread.

I've just looked up my books on classical harmony and the reason that the third is often omitted is because it's the note that the 11th usually resolves to.

In BIAB, I always think of the 11th as 9sus4. I often notate it as that. If that doesn't sound good, though, because not all RTs have this chord, I will then use either Gm7/C or Bb/C (for C11 as an example).

Regards,
Noel
