Of course if I ever decide to do a TMP Enterprise, the X layout would match perfectly with the diagram in the turbolift in TMP.
That layout seemed awfully convoluted to me. And IIRC Rick
stated once on this BBS that he threw that together pretty fast, without having time to really lay it out rigorously.
I actually like the simplicity of your layout. It is similar to what I have sketched out, though a little more involved. And mine goes the 45 degree offset, "x" route, but not nearly as involved as on the turbo map from TMP
