Thanks for posting these pics up OP.
I've pretty much switched from all metal to all plastic for mechs.
Your pics have shown that there is usually very little if any loss in detail.
That's something I was concerned about.
Meanwhile the plastics are far lighter to carry, more durable, and honestly a little
more economic.
My Feldherr bag full of plastics is so light I have to double check to make sure
it's slung over my shoulder while I'm carrying boxes of terrain.
My old Plano Regimental Command Box of lead and pewter Parthas is FAR to heavy
to carry safely and requires a trip by itself. It's to heavy to be practical.
