Best and lightest way to build a 8x4 board?

Thank you, all food for thought. It's pretty darn complicated this model railway lark.

Most aspects of the hobby are not that complicated - but your start up issues come down to managing around a layout for an OO gauge HST bookset that really requires 12 feet x 4 foot 6 inches when you are limited to a put up/pack away setup.

Well if I do the 1 piece 8x4 I'm hoping the boss might decide it's too difficult to lift it in and out and she'll let me wall mount it.
