Nice!!! Try slapping any exercises you're working on, scales, etc...slowly, with different rhythms, 1/8-triplets-1/16th's, making sure you're really hearing each note. You can also try slapping and popping octaves, for example, on the A string:
D-B-C-C#, slap the A string and pop the G string octave, then move the exercise to the E and D string, A-F#-G-G#.

The key is looping your ideas, and playing groups of notes that work well together, the above octave ex. is kind of a throw back to the disco era.
