Turns out I'm either smarter or dumber than I appear
I actually hung an oval 3-LNB dish when I switched to D* from E*. I had forgotten all about that; when I went out for my morning run, I checked via eyeball and got a pleasant surprise. Whatever points I get for prior preparation are probably erased by asking a dumb question (but thanks for the answer!)
Always go with dumber, that way you surprise even yourself, this is a perfect example. Plus people will underestimate you which is always good, you can always live up or down to their expectations.
