I was just wondering which would be a better investment. 2 doz shells at $50 a dozen, or 1/2 doz fullbodies at 69.99. I already have 300 texas rags, and a doz old magnum duck shells that we painted up to look like snow geese. Would the birds rather see the 2 doz shells or just 6 fullbodies. I want to get some snows this year so your opinion is appreciated.
