delete data from table without rollback/logging?

Hi group, I'm running a cut down script on a copy of a live database to remove some 90%
of the data.

Currently I use delete statements to remove the data from 100's of tables.
Another method I can use is to copy out 10% into a temp table, truncate the original and
then copy the 10% back in, reducing the hit on the rollback segments.

Regardless of which option I take, is there a faster option to delete and insert data without filling up the rollback segments.

I see 'alter table xxx nologging' doesn't seem to be affected by deletes.

Ideally an 'alter session nologging' statement would be useful.

Also, I would have dedicated use of this database, if that helps with any ideas.

Cheers
