If scanning is the main objective then you may also want to consider C41 films. Ilford XP2 scanned very good in my 35mm film scanner and at EI100 it is very fine grained. Scanning regular BW films in my Nikon Coolscan IV-ED gave more grain. Plus you can't use ICE on regular BW films. Don't know if this all applies to drum scanners as well.

Nice shot of Old Montreal.
