Agreed Fiddler, and a lot what you say makes sense and different tubes *do* sound different. However, you'll notice that what Mick proposes with tube swapping is changing the type of tube to alter the sound, say from a 45 to 300B rather tube rolling within the same type.
That said, I suppose it is common knowledge that some tubes within the same type are better than others, the Western Electric 300B being a good example of a universally praised 'best of' 300B. With Mick's preamps all I'm saying is that they leave the factory sounding pretty good, and a lot of us have found for example that his chosen EH-6SN7 seems to sound just as good (if not better) than the drawful of expensive Kenrads/Sylvania VT231's some of us have ended with!
In the end, I do agree with you that you need to trust your ears and if tube rolling or cap swaps give a perceived better result - then thats all that matters.

Steve.
