Digital BW, The Print

All,

I was told once that a useful workflow is to shoot color film to 
produce B&W prints . . . that that procedure offers more control than 
shooting B&W originally.

Two questions:

1. Do you agree? What is your experience with such workflow?

2. What do you then find the best way to translate the color to B&W? 
Selecting on of the channels? Blending channels? Using Grayscale? 

Sure would appreciate any input. TIA.
