What i do for 100% GS (or 99.9%):

21: 4 drums, 4 sparkles

37: 5 drums, 4 sparkles

38: 9 drums, 4 sparkles

Usually put extra drum on flagship. Not sure if that has any effect. Used to be able to get 100% with only 3 sparkles on 21, but it seems to have changed since it was first introduced. Anyone else have any ~100% compositions? That might be a good place to try to figure out what we should do to ensure GS.
