I vote for LOD...same ancestry, and it seems to work for this usage. A couple models ago I had a robot that was a pretty light 8K or so, but, for use in such things as giant robot army scenes I did a part-for-part replacement with simplified and optimized parts to get it down to a third of that. I called that the "LOD2" version (and was thinking of adding a LOD3 at 800 polys or so!) Pity we can't animate a LOD function as well as game engines do, but is definitely useful for Poser. Also smaller tex maps...I reduce most of mine, using the smaller ones for all but those face close-ups.
