SP said you tend to see a lot more natural turns in standard, so we started today with my LF moving back first. So almost every time we got in frame, I started with my weight on my LF before remembering to switch).
May I offer some advice as a leader with knowing what foot to be on since I am also always working on how to clearly communicate that.
Instead of thinking about which foot you should be on, instead learn to feel which foot you should mirror from the lead (ignoring same foot lunge position for now, but it does apply here as well.). You are connected at the ribs, hips, and possibly the thighs depending on school of thought (some teach a weaker connection there). If the pro puts his spine over his left foot, you know through your rib connection where his spine is located relative to his hips and thigh and ultimately his foot (note also I'm assuming vertical spine with limited or no sway . . . at higher levels, my spine description becomes the lead's center relative to your center). Thus, there is no remembering what foot you need to be on, but rather feeling it to the point it happens automatically through muscle memory. (PS: notice that I didn't say anything about arms / hands since they are not really needed, but do think about how things might apply to smooth and how one would use that connection to feel location of weight!)
As a guy, I've had to learn to be clear for the foot I'm on. My partner(s) and I have done drills where we have our feet together (risen or lowered / vertical and swayed) with the goal of communicating location of weight which comes from moving the center only inches. This is important on a comp floor where floor craft or other issues means some sort of modification with the partners needing to be in-sync to make it look clean. Note also there are many variations of this drill with being able to monitor one's weight between feet.
Standard is just so cool and amazing with two people moving as one. I'm always amazed watching the leg action of pros doing foxtrot (usually continuous reverse wave) where both are wearing pants . . . especially all black. The silhouette is glorious as legs and weight move as one while the bodies breathe in unison.
