I recall recently reading a thread about someone having difficulty with the truss tubes on their Lightbridge moving out of place in the socket when the clamps were tightened down. I'm not saying that this is an issue with the Orion Dobs, but it's one more thing to look at.

I'll also second mayidunk's suggestion for checking whether the spider bolts are tight. I had that problem before and was mystified why my collimation wasn't holding until I noticed the spider flexing abnormally when I was adjusting the secondary. Tightening the vanes fixed it right up.
