i think for the usa and how they go about the team selection or member assignments they should at least verify that the team member has the proper accreditation to do so.
Having a team trials for these events would vastly improve the knowledge that they assign the rite skier to the events they are qualified to ski in. i know of a number of overall men 3&4 that can trick near 8k, jump near 200 and don't mind 36 mph..
Having team trials also gives a true acknowledgment through out the sport as a whole as the selection team gets to make a selection decision based on game day performance and previous qualification.
I guess if the powers to be in the sport did anything productive and useful, we would not have anything to bitch about...
