There is a "first rib mobilization" technique on a web page that I think I posted in that thread. You can also search google and youtube for that term. I also made up one myself which I describe in that thread.

I understand what you're saying about the testing.

Re: coldness, I've heard both chiros and MDs say that's nerves, but I don't see how it couldn't also be artery.

I wish there was better and more standardized testing for TOS. I don't care if it's complicated. Make a flowchart, medical community. It's 2012.
