In reply to Michael Gordon:
> Think the system works fine as it is. Just because some info (tech grades) has been made available, doesn't mean that more info needs to be.
You're right, of course. No info really 'needs' to be made available.
But once we got E grades we wondered how we ever managed without them.
Once we got tech grades we wondered how we ever managed without them (although for some reason they 'weren't needed' below 4c.)
Once we got tech grades below 4c we wondered how we ever managed without them.
Once we got star ratings we wondered how we ever managed without them.
Once we started using French grades for sport routes instead of UK Adj grades we wondered how we ever managed without them.
Once we started using bouldering grades instead of UK tech grades we wondered how we ever managed without them.
Etc., etc.
That's how we've ended up with such useful guidebooks that cover all kinds of climbing styles and give loads of useful info without needing to weed the hyperbole and the understatement out of often cryptic text descriptions.
In a sense I think it's a shame that the old-style charm of text-rich guides has been eroded, but looked at objectively a guide is mainly trying to help you make good choices and much of that can be done by grades, stars, etc rather than needing lengthy text.
My prediction is that one guide soon will introduce Adj grades for each pitch and that soon afterwards we'll wonder how we ever managed without them.
I may prove to be wrong.
