But can the trails be labelled correctly then? Bunny is rated black - seriously? Even the original line was never black and now it's bobsled easy. Bobsled and Bunny should be green. The new Espresso (which should be given a new name as it's not even the same line) is probably a blue-green but I have yet to ride it. Basically the rating should be related to the difficulty of the trail and not a past trail difficulty.
Bobsled should be green/blue and bunny has enough on it to make it a blue :) Expresso should be blue. Agree with your other comments.
Also, trails should be rated in relation to other trails on the same mountain. For example, a Cypress ski trail rated a black is probably a blue on Whistler.
