27th Lancers Alumni Marched 10 or 12 in '94. They sounded awesome. The sound is nice and dark and it's hard to make them edgy. They don't cut well but combined with mellos they sound great.
Corps used to need them so they could play some of the chromatics between Baris and Mellophones, without having the Baris play above the staff the whole time. 3 valves changed that. Plus better musicians coming into the low brass sections.
