I think it would meat great resistance anyway, Firstly people in general are afraid and often reluctant to change even if for the better. that's just human nature.
But from an economic point of view I don't feel resorts would cooperate. What resort is going to easily degrade blacks to blues or double blues to single or blues to greens, whatever without great fight. They all want their image/prestige to be of the highest it can be. I personally think ithat actually can fail to some degree but none the less they want the prestige.
I actually disagree to some extent, in that resorts want to be appealing to ALL levels. If there's fudging, I suspect the fudging is in the direction of having a balanced "portfolio" of runs. This is the only way that I can explain why Breck calls the upper parts of its new Peak 6 runs "blue." In comparison to blues on peaks 7-9, it is solidly black. IMO of course.
