Thanks for the illustration Van! It really helps! If I
have to nitpick though, it's three points:
1) The 5 segment SRBs use dummy segments in order to match the length of the 7 segment SRBs, as so to simplify the Core Stage somewhat.
2) I had expected the SRBs to be mounted a little lower, so the exhaust plumes wouldn't risk harming the SSME or the SSME support structure. Though I'll admit that being a regeneratively-cooled engine, it may not matter too much, while a protective cover for the SSME supports can resolve that department.
3) I hadn't actually factored in a no-Centaur Upper Stage, so it came as a small surprise to see it here.
But these really are niggling issues, and really don't detract from the work you've done. Which I thank you for again. Almost exactly what I had pictured in my head.
