Ah well... that changes my advice then. Since your smallest unit of backup and recovery is the *database*, how you break that database up into data files becomes a matter of utter irrelevance.
I favoured 2GB data files because in archivelog mode, that is then going to be the smallest possible recovery you can ordinarily do using O/S commands. But in noarchivelog mode, you're simply going to restore *everything* from last Sunday night's backup regardless. So you might as well go with the biggest data files your file system will permit.
