I can't see any problems, since they change the name when they change the source. There's Arista Premium, Edu, etc... Different films, different names.
You just don't know how lucky you are over there! A 100 ft roll of TriX costs about 60 euros over here! It's just a tad cheaper than buying preloaded...
That does make it a little easier, except just as soon as you get everything working just perfect with a film it's gone, because the contract ended.
