How do you find substitutes for rolling? (that are unlike the tubes they're replacing)

Russ57's post responding to mine got me wondering... he mentioned using 6CG7s in a 12AU7's socket. I looked it up with the TDSL program (don't know what it stands for) and that tube isn't just not a replacement for a 12AU7 -- it's got a different pin-out, too. How did he/general knowledge stumble across the 6CG7's being a perfectly good substitute for a 12AU7?

Is it just a matter of trial and error and best guesses when it comes to preamp tubes, or is there a method to it? If it is, it would be awesome to get one of those cracking huge lots on eBay and start plugging every nine-pin miniature I can find in to see if it works. But I know it can't possibly be that easy, and I really don't want to fry my equipment. I've also got the feeling that 95% of those lots are worthless crap, but whatever.

I'm looking to be right adventurous in all this, but not stupid. Thanks.
