Option 2. Legs off, head folded down and strapped to the body, standing upright. At least that's how manufacturers do it. Seems safest because nothing could fall into the glass at any angle, whereas if it's laying down there are still portions of glass that could be hit.

As the above post gets into... it's sort of a dice roll regardless because of how shippers are. I was talking to Steve from Pinball Refinery and he told me about a LOTR he did that got skewered by a forklift straight through the coin door... lifted the under playfield rails up and through the playfield itself. Totally destroyed every part of the game

I'd still do my best, get insurance on it, and cross my fingers though.
