Heddon torpedo question

[Paulpro]

Dave ,hi,is it safe to guess the smallest prop on the chart is the correct size for the teeny torpedo?.I understand they make some for fly fishing,I wouldn't want it to be too small either.For now I will stick to a single prop,later I will upgrade.At the moment I have a couple lures with no prop which I had removed for the double prop technique.[fishin]
