Sorry man, but I don't like it.
Not trying to be critical of your technique, but I've been using milkweed for over 30 years so I speak from experience.
1st off, with any type of container that isn't attached to your body, you have to reach for it...too much movement. You want milkweed as close to where your hands are...pocket/chest/belly area. You often need to release a floater when deer are in your lap. Doing so may help you determine the risks of waiting for a better shot. Moving your hand against your body to reach a floater is much less noticable to deer than reaching out away from your body.
2nd, what do you do with the pill bottle lid each time you pick a floater? Lid on, lid off. Is the lid tied to the bottle? Can it be dropped? Just something else to deal with.
30+ years of milkweed...keep it in the pod. They will float better.
