Yup, honey comb everywhere except for where you have fasteners. The honeycomb actually has excellent compression strength except for the edges (anywhere you cut a hole in it). It does not hold screw either, so that is the second reason to use ply/foam around rodholders, cleat, etc.
I would use 3/4" core, its really just barely heavier, but much stiffer than 1/2" core
