Question concerning RAID0+1 and redo logs.

We are in the process of installing new disks and upgrading our software and I was looking for some opinions and/or facts. We are upgrading to AIX 4.3.3 and Oracle 8.1.6 on a basically OLTP system. We will also be adding SSA disks with a RAID0+1 configuration. My questions are :
In RAID5 it is recomended to put the redo logs on raw devices, now with RAID0+1 should I do this?
Is the performance or RAID0+1 good enough so as not to effect my redo logs?

        Are there any other files (ie, : rbs,archive logs,temp, etc) that I should consider not putting on RAID0+1 also,

        that is if the concensus is to leave them off? More questions to come.
Thanks
