OK, I was actively involved in Drum corps from 86-96. A member of PR from 86-90, and on staff with various corps 91-96, so here is my opinion (and let's all keep in mind it's just an opinion)
86 - BD won and was in my opinion the most popular
87 - Cadets won, but SCV was more popular. (87 cadets is my fav. of all time by the way, not counting the shows I was in)
88 - Madison won, and was very exciting, but I think SCV had a better show (WAY better than 89)
89 - SCV won, and regardless of how the poll came out PR got much better crowd response (having been a member of PR and seeing SCV that year). I will also throw out that Cadets, while finishing 5th were alot of peoples favorites with Les Mis. 89 was an awesome year all around.
90 - Cadets won, and I will be honest and say I didn't think anyone had a really great show that year.
91 - Star won, but most people liked Cavies and PR
92 - Cavies won, and were very popular, I prefered cadets
93 - Cadets won, I again prefered PR
94 - BD won and was, if I remember, almost everyones favorite, what an awesome show.
95 - Cavies won in a bit of a surprise ending to the season, BD was undefeated going into finals week. Lots of great shows that year.
96 - PR and BD tie. PR was a HUGE crowd favorite, and coming from behind (4th in qrtrs, 3rd in semis, tie for 1st in finals) made it a great story.
Well there ya go, feel free to flame me if you like, just one man's opinion
In regards to this year, I attended a cinecast of qrtrs and PR got the best crowd response by a long shot.
