Same here. :)

In complex environments I might have two data data structures (for
header and detail information).

For header / detail situations, I send the header data via a parameter structure and the detail via data queue ... the detail structure is defined as an external data structure (which java uses via RFML) so both the RPG and Java structures are always the same.

It depends on how I'm doing the impedance matching. If I send or receive all the detail at once, a data queue is nice. I have other situations where I send/receive the detail one record at a time (first I send the header, then each detail). In that case, I use two data DS's, but the control DS tells me which one actually has data. It isn't perfect, but it avoids an extra queue. Of course, the additional queue could be either a feature or a bug depending on your design requirements.
