Hi Mike,
I use insulation foam board its light and very easy to shape and builds up quicker
Any track to be laid over it can be cut into the foam creating a cutting easily ...... drill holes for the wiring thread a tube in the hole put the wire in down to the underside of the boards ...... saves loads of time trying to thread wires.
