First of all, I can tell you that WW are not popular at all with the instructor's caucus. The brass guys arn't about to give up trumpets for clarinets. I know this having spoken to many instructors.
Second, instructors vote because they would like to have the freedom to try new things. That is all. Contrary to popular belief, very few people can make a decent living from drum corps. With the exception of a select few, very few people can do DC as their primary career. An example.. GH's salary is normal for a head of a non-profit of YEA's size. He does not have any personal endorsment deals. Last I checked, he drives a 2002 Eord Expidetion with 300,000 miles on it.
Finally, if you now hate drumcorps, leave, and quit #####ing about it here.
