Well, it all depends on the sensitivity. One of the good things is that since it is processed by inspection, you can "cheat" a bit and use a custom contraption (I saw this in Shutterbug years ago) to get perfect development.
You need to make a glass shelf (angle iron and rubber feet work fine). You put the developer in a glass plate or a piece of white pyrex cookware (like a lasagna dish). To control development, you then put the safelight on the ground under the shelf. Once you like what you see, just stop and fix... Since they're rolls, you can start development using a see-saw technique and once the images start to appear, you can cut them into strips of 3 frames (so they will fit perfect in printfile sleeves) and process the pieces one by one (putting the others in a bowl of water to slow development).
As for developer, you could try Dektol first...
