Digital BW, The Print

I currently use a 1280 for color, a 2200 for B&W and a 7600 for large 
prints of color and B&W. All with Standard Epson inks & photo black.

I'm  considering the R2400 for B&W only,with standard Epson inks.
I've never used matt inks or paper (since giving up a wet darkroom), 
partly for the ink change hassle and partly for the loss of detail. 

I'd appreciate any one who has been using it for B&W would share their 
experiences and thoughts about the R2400, including the ease (or lack)
of changing between photo & matt black.
Thanks,
Donald
