Can't really go wrong with Velvia. That film is sex embodied in emulsion form.
You mentioned in your blog you looked forward to see how much detail is in the scans: well Velvia 50 @ 160lp/mm is extremely capable. Lets say you only pull 80lp/mm out of that though (which is probably a reach) and are targeting around 4kdpi as a resolution to use for scanning:
2 * 80lp/mm * 25.4mm/inch = 4064dpi
4064^2 * (60 * 170)/25.4^2 / 1024^2 = 250Mpx
So if you had a 4kdpi scanner, scanning at 16 bits a channel, you'd be looking at around 250 million pixels, for a total file size of 1500MB each.
Velvia regularly bests even the best scanners out there. In order to extract all this information you'd have to use a drum scanner. But keep this in your mind for the next time someone asks how it rates next to digital. :-)

Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
