Every other factor is the exact same for this hypothetical hunt, if you had to choose between these options which decoys would you pick to hunt a stubble rice field?

12 Full Body Snow Decoys
48 Sillosocks Snows

add a zero after each number you put up there and it would be worth considering answering that question

This for sure.

What they said. Otherwise pray for fog and pass shoot

Going along with the above responses, the silosocks and your still taking a leak in the wind.

I agree with the comments above, but look at it more like a challenge. If you had to choose between the two options which would be the most effective?

Hunting adult geese in small groups coming out of the marsh and hiding in a hedgerow on the edge of a field that they are using the full bodies are going to work if they are very visible in a field.

Hunting large concentrations in a thickly stubbled/cover field with birds feeding the middle of the field in the early season the sillosocks will work better with good wind conditions.

But that is going to be a hell of a challenge
