Great explanation here...good luck http://www.youtube.com/watch?v=Q6U5okNdGiY
First play rL r L, then double the middle r:
.1 2+ 3
rL rr L
Work on making the phrasing more flowing by playing all strokes at a similar rhythmic value -- essentially as a group of five -- like this:
1 2 3 4 5
r L r r L
Play the previous two rhythms back to back in different tempos and try to make it flow nicely. Orchestrate the strokes any way you like.
Why isn't it just called a flam drag? Why make it a Blushda or Tony Williams -lick or anything like that. It's a basic rudiment.

The flam drag's sticking alternates and the blushda's sticking doesn't... but that's just splitting hairs.
