you make it sound like some of your partners feel like there's a reward for finishing first! because you used the phrase "masters of the steps" it seems to me that part of the issue could be how the class is being taught. it is my personal view that dancing is not about "steps" - it is about leading and following. but it could be that your class is teaching "steps" and you are essentially doing a pre-set choreographed routine with each partner every time you rotate - this is the only way your partners could know for sure what figure is coming next. if this is the case, your best alternative IMO is to find a class that emphasizes lead & follow over "steps". if there are no alternative classes, perhaps you might asking the instructor to let the leads choose which figures to lead vs. doing a pre-programmed sequence. then those partners won't be able to anticipate the figures.
