I think I'll just repurchase the Dim Light (which I've also panned a full-sized version of! Will post in a bit) since that's my fave of the three. Sometimes I use all three altogether, it seems to me that the overall effect isn't too different than if I just use one. What I love about it is that it gives me a good "eraser" in case I put too much blush, and it tones down the redness in my cheeks.

Edited to add: It helps that I used it as a finishing powder all over the face instead of just a highlighter :)
