toss and wait and see is a good approach. You probably will see 80% immediately gone and the rest slowly over the next 30 min will be cleaned up.
I too see amazing response to optimal and I only hand toss it when I have time.
A trick that is working well for me (and would be a very smart marketing trick if anyone from Optimal is reading this..) I bought the standard optimal and the next size smaller (the JR.) and mixed them 50:50. This gives a variety of sizes that more fish can work at at the same time. The larger fish take the bigger ones and the minnows can work over the smaller ones and get them in their mouth more quickly.
I know Purina has had success with a feed that has multiple sizes, Optimal could easily have a feed with 2 sizes mixed, or even 3 sizes mixed using some of their starter pellets.
