I haven't used the "World's best" method yet, but it sure sounds good. I use Pro-Cure or Pro-Glow. When I add oil such as Mike's Shrimp oil, I find that the eggs are a little harder, they don't seem be as large as the original size, and they don't milk out as well. My favorite is a water soluble scent, or Bio safe scent, such as Smelly Jelly Sticky Liquid, or Berkley PowerBait liquid. With the Powerbait, the eggs seem to swell past the original egg size.

I think if I were to do "World's Best" method, I would apply the scent to the eggs after they leave the strainer, oil and water don't mix, let them soak in the scent for awhile, or apply the scent to the eggs when you reach your fishing water. Hope that might help, and have fun. Jon
