Rich - Could you point to the place where Robert states that bit about controlfiles to trace? Thanks.

I believe that an 'alter database backup controlfile to trace' loses the RMAN data stored in the control files if you're not using a repository (if I remember right from RF's book).

Since we're not using a repository, we've got controlfile autobackup on (in 9i use 'configure controlfile autobackup on'). We dump these disk copies via filesystem backups as a safety measure. We also do a backup database, archivelogs, and then control (but all in one step; I'm not sure I'm clear on the reason for separating them into three backup sets)....
