Thanks for the info John. Perhaps color film has different properties that make it easier to flatten out. I've had the roll hanging in a closet with a weight on the end for a couple weeks and it still curls up. I'll probably end up cutting the roll up and storing them flat in a negative holder. Scanning them will be a problem but I think a piece of glass cut to the scanning area dimensions will do the trick to keep them flat.

I'm currently using a Microtek 48 bit scanner that can do up to 4x5 and although I haven't used it much, it works very well for all around scanning.
