Digital BW, The Print

Does anyone have any favorite Duotone presets?  I know how to construct these, but am wondering if there any great ones that have been successful used for fine book making.  I recently made a Blurb snapshot book and converted all old B&W snapshots to duotone in a warmtone.  Nice....but for my own photographs I am wanting a more subtle preset.  

I am particularly interested in a more modern subtle split tone, ie Selenium toned simulation.

I am not that impressed with the ones prepackaged by Adobe.  Any bookmakers out there with opinions or presets they would be willing to share.

Thanks in advance.
