Kicked in the Grace (2007) is a four-measure flam étude that employs a myriad of grace-note contexts: flam-accents, flam-taps, swiss triplets, inverted flam-taps, etc. The scope is broadened by adding drags to produce different variations.
In a line setting, the variations can be chained together as appropriate. Additionally, the snare and quad parts, by ending on an eighth note upbeat, allow "off the left" variations to be seamlessly added to the sequence.
