I'm concerned spiral and circle are far too similar in sound - particularly the rise/fall pattern - for those with any hearing challenges. I also accept the criticism of the similar terms (eg: vortex) as implying a progressively closer approach (which really only applies in a "meltdown" situation) or fostering the idea of twirling/spinning while doing the primary move and that likely extends to swirl.

At the risk of offering one more straw dog, there's "loop".

"End that star [left] facing your next neighbor, loop right [around] that neighbor and continue into a swing."

"Two ladies loop left once and a half, _insert_call_here_ your partner."

To my knowledge, it's free of call/cue homonyms, sounds short and distinct and the other use in contra ("with your partner promenade across and loop wide to the left to face a new couple..." is a similar concept. No obvious negative meanings in common language (most are positive, e.g.: "in the loop").

Eddie is also a gender name, thus I would rule that out. Vortex doesn't exactly come off well on the mic. Swirl sounds way too much like circle unless you are none ciating very very crisp late, in which case you are going to get some Pardes sounds hissing on the mic.

Thus, I don't like any of the three. I suggest spiral instead.
