I like high contrast B&W. I used to use the Monochrome + Red, but for most scenes I shoot, it's too contrasty. I find the regular Monochrome is best all-around without always having to switch between different B&W profiles. +2 on Shadow and +1 on Highlights. I used to set Hightlights to +2 as well, but, again, in some scenes, highlights tend to get overblown. +1 gives me some headroom.
