I'd properly develop and expose for normal contrast, and add the contrast when printing. Then you can have the potential for multiple contrasts for different uses. Scanning will work better with normal contrast negatives, at least with an epson. Some scenes you might want a little more shadow or highlight detail later on, which might not be as easy if the negatives are high contrast. Just my personal style. I've mostly used tmy2 and d76 or xtol for random convenient shooting. Tmy2 is more expensive than the various low budget tri-x clones, but it's very consistent quality and less grainy.
