these are layer 1 and layer 6, and layer 2 and 5 are solid GND.
I was referring mostly to layer 3 and 4. The diff pair is either on 3 or 4. If it is on 3 a slab of GND should be on 4 and vice versa.
It's 1. Vsuply + components 2. Ground 3. HF 4. HF 5. Ground 6. Vsuply + componnents
Right?
If tight for space you can use 90% corners with a chamfered outer edge. I suppose the chamfer acts like a mirror.
i'd *really* prefer not to do that :)

wow that's pretty bad-ass.
Yeah I had read a more extensive guide in a TI pdf somewhere, can find it at the moment. But TI documentation also schizo's on curves vs. corners of 35 degrees and chamfered 90 degrees.
