Replying to Your thoughts on B+W and Chroma Limits in skis edits.

Title pretty much says it all, I'm working on an edit right now, and I want to try and use some B+W shots and some limit on chroma shots (when just one color shows and the rest is black and white - I know most of you probably already know that though) and I want some opinions on what you guys think. I'm only planning to use it for like 3 or 4 shots, and not for the entire shot. Let me know what you think.
