The reply of vbuehringer isn't to be taken seriously.

Yes, you should use redolog duplexing, and two members per group should be sufficient.
Those files should go to different drives, on different controllers. The loss of 2 members of a redolog group is completely unlikely, unless the data is on one disk, or on one controller. Hence your transaction can be recovered.
