I marched in the Rutgers drumline 05, 06, 07, 08. The only year Dennis was involved while I was there was 2005.
I marched 7 years of drum corps. 3 of them were in a top 12 corps. There are also many people at Rutgers who have marched in various corps such as Surf, Madison, Boston, Crossmen, and Cadets just to name a few.
I know we would learn 3 shows throughout the season, pregame show, stands grooves, cadences, and numerous other things. The beats Dennis wrote for us was what was needed to memorize quickly and get the job done. I would even say those lines that you mention are not even at the same difficulty level as world lines. I have friends there and it is a similar way. In some ways college band was sometimes harder mentally because you had to learn so much music in almost no time and strive to perform at a high level.
