Digital BW, The Print

I am having similar problems.  Could someone briefly summarize a 
proper B&W workflow from a digital ProRGB workspace color file 
through printing in QTR.  

If you have a color image in ProRGB, should you make it B&W using the 
channel mixer or just converting to the Gray Gamma 2.2 workspace? 
Does this hurt the image?  

So far the images that I converted from RGB directly to Gray Gamma 
2.2 and printed through QTR have lacked dMax compared to images 
printed on a R2400 through AB&W.  The problem with AB&W is that it is 
a game guessing what the B&W will look like unless you have made a 
custom profile for AB&W.

Thanks,
Ryan
