The two components of the trad system aren't fully separate - the adjectival component already encapsulates some of the information being given by the technical grade. In other words the adjectival grade is already defining a relatively narrow band of technical difficulty; the tech grade simply adds to this information by giving the technicality of the hardest move.
Thanks for the lesson, but I'm afraid the two elements are NOT directly linked. Yes, moves of a certain difficulty usually go with a certain territory - I said that in the OP.

Correct again - thats what I'm after!

Why? There are already examples of it, you said so yourself. I'm just perplexed why there aren't more. Have you never been on a route that has a really hard start which has been technically undergraded purely to avoid something like VS 6a. I just don't see anything wrong with VS 6a.
