I have a question about what gets backed up and where when you do not use the cotalog. Currently I use a catalog and perform a level0 each Sunday nite and I can justify the datafiles and size of the backup. If I perform a level1 on Monday nite the size of the backup is small justifiably. If I use the controlfile option for a level0 what would be the size of the backup data? Would it contain all datafiles? If it perform a level1 with the controlfile does it still backup all the datafiles? Does using the controlfile not backup any datafiles and you have to back them up seperately? Off to purchase Roberts RMAN book to get some answers and shake up the grey, gray matter.

I found that it is still much better to use a catalog rather than depend on the controlfiles. The bleeding edge is not always comfortable. There are some things that become nearly impossible to do with out a catalog. One thing is that the controlfile doesnt' do an auto controlfile backup of the controlfile at the end of a backup, therefore it only knows about the backupsets from previous backups. I don't know if this speaks to your questions, but I know that after having to manually and painfully recover a couple of times I switched back to using a recovery catalog. Then you can duplicated a database to another server with ease.
