Haven't seen a lot of new posts lately, so here's one I just taught last week (my first post!). Self-reversing, 32-counts - some steps were taken from previous posters (thank you!) but made into different combos.
*Tiny turn - lead with inside leg, it's a turnstep off the short end of the bench.
This combo gets you facing the rear of the classroom to start over again on opposite leg lead.
*Shuffle forwards on long (back) end, straddle. Other leg leads with shuffle backwards on long (front) end, straddle. You can always take out the straddles and just shuffle x2.
**This is just a knee/straddle, knee/off (towards front). Make sure to teach that the outside leg will lead the mambo step (you turn body into step and mambo on floor).
*Mambo on step, shuffle to rear. Mambo other leg on floor, shuffle back to front.
That's it! Breakdowns are fairly easy, and the toughest combo is at the beginning. Can always add some power to up the intensity!
