I love the Stephen F. Austin drumline because they have Ralph Hardimon as a "tech". Imagine that? A legend drops by your rehearsal from time to time and shows you how to become a better percussionist. Absolutely amazing.
Clear Brook has a great line and I wish they would feature them more often in their shows.
Westfield has an awesome line this past year. Their show definitely featured them well.
Churchill's drumline should be back to form this coming season. There was some.....unpleasantness with their previous instructor in 2005, which lead to the line not having rehearsal for most of the Summer. Fortunately, Jim Ragsdale (Percussion Tech for The Cavaliers) came to the rescue and has done a fantastic job so far. Plus, they'll have a consultant or two coming in this season to make sure they have the best product possible.
