Morph targets are you're big enemy. Pz3 files do NOT store geometry unless its custom geometry and only in poser 4. They reference the geometry from the obj file in the geometries folder. What does get stored are geometry for props and morph targets. V3 morphs are huge. The morphs to adjust clothes are even worse at times. A few things to cut down sizes are 1. Using magnet packs for body shaping instead of morphs. I use magnets for body shape and only use morphs for facial expressions. The magnets do a real good job at shaping and shaping the clothes to fit plus you can change the body shape around without needing more morphs. 2. Delete ALL unused morphs. 3. Compress morphs into one body style. I do this on my older vicky2 figures. Basically get the figure the way you want the do a create morph on very body part that's changed. The make that a new full body morph. Now you can delete all the old morphs and have just one body shaping MT. I don't do this with v3 since her mesh is more dense and so a full body morph for the shape I want can get spendy memory wise. Plus I'd have to make body morphs for any clothes I stick on her.
