Digital BW, The Print

Hi all,

A few weeks ago, there was a thread on the topic of shooting digital 
vs. film.  I have the good fortune to be going to Australia in a few 
weeks and plan to take tons of photos.  I'll be taking my Nikon 
CoolPix 5000 as well as a traditional 35mm camera.  My question is 
about the best 35mm film(s) to take for later scanning and making 
digital black and white prints.  (I know I'll be shooting in 
extremely different lighting conditions and will be taking my tripod -
- rainforest to desert sunlight.)

Has anyone worked with the chromogenic films -- Ilford XP2 Super and 
Kodak T-Max T400CN?  How do they scan and do you like the resulting 
black and white digital prints?

Or, should I shoot everything in color to keep all of my options open 
and then just convert the images in PS7 use the channel mixer for 
those that I want to print in B&W?

I'd appreciate some advice and would like to experiment with the 
films before I leave on my trip.

Thank you in advance.

Bob
