If it’s just a straw poll to reduce the options to a binary choice, to be decided in a formal setting, then they should have spelled that out.
When I was on an executive committee with over 100 units and we wanted to canvas opinion on a range of options we asked people to indicate on a form 1) their most preferred option, 2) acceptable options, and 3) options they would not support. Then we added a space for comments.
In the case of the original post, with only 8 units, could they not just call everyone together to talk about it, perhaps over a morning tea or evening drinks?
