I used to a dance with a guy from FADS, and it bugged me out that he'd start his American Rumba on the 3 beat. I kind of wanted to hit him every time.
No wonder men are afraid to dance...
for fear of being smacked just doing
what they were taught. In this case the
FA leader must be starting forward on 3.
In addition to FA teaching q-q-s on 1-2-34
and AM teaching s-q-q on 12-3-4, there's
the issue of what count is best for starting.
I'm of the opinion that starting on a side
step (1 for FA and 3 for AM) is physically
better because the leader gets the follower
going in a much smoother manner. The
figure 8 at the hip gets better prep, and
there isn't that awful forward "attack." Somewhat similar to preps in Standard
or even WCS (before backward step in
this case).
Then there's the music issue where
some Rumba tunes just align well with
q-q-s and others s-q-q (on 1234), but
most work decently/well either way.
Similar to Salsa on 1 verses Mambo on
2.
