9volt. Days have gone by and I had a new thought. Maybe you could view concert percussion as a "color instrument". In the wind sections the oboe and bassoon usually are not "dominate contributions. But the do solo from time to time. So why are they their? because of their "sound color". So when you a few measures of this and that of percussion "sounds", it is where the composer is creating contrast of sounds and effects. Now I know that that is not as satisfying as a through composed percussion ensemble, but it dies perhaps give you an understanding of the important contribution of the percussion sound "tid-bits".
Just something to think about.
