The floaters will do, just make sure they are all upright and not tipped over from the keel. The problem with floaters in a field though is their low profile, they are really tough to see. It's almost a necessity to have some form of spinning wing deek. You didn't say you had any, but I'll throw this in anyways, if you have any Canada geese deeks throw them out too, their large size will help out with the visibility problem and ducks don't seem to mind them at all
I love my job, it fascinates me. I can sit and look at it for hours.
