The beauty of RMAN working with an MML is that it knows how to get what's needed for a restore. If you're staging to disk then you have to be able to figure that out in short order and possibly while under duress. If you're going the disk staging route be sure to develop and practice every conceivable recover scenario. I would document each recovery scenario so that when (not if) you're in a recovery situation you'll know how to proceed. (Of course you should practice recovery regardless of your setup.) Staging to disk may require a "double recovery" where you have to recover backup files from tape to disk then recover the database from the backup files.

Losing data is more expensive. Ask damagement if data loss is acceptable and if it's okay to take risks on backups. If damagement wants to take shortcuts on the backups then confirm their decisions by memo from you to them outlining everything. Keep a copy of that memo. And it would hurt to let damagement know that you're keeping a "correspondence folder." ;-)
