Distribution of datafiles over disks vs. striped volume

We are planning on installing Oracle 7.2.2 on a HP9000 K200 dual processor machine. The machine is currently equipped with three disk in an LVM (logical volume manager) configuration.
There's 2 ways we could distribute datafiles/tablespaces over the disks. Either we explicitly put different tablespaces on different logical volumes that reside on different disks, or we create a new logical volume striped over all 3 disks especially for oracle datafiles and place all datafiles in there.
Hans anyone ever done any performance comparisons concerning those 2 configurations? Any recommendations are appreciated.

HP-UX 10.01 stripes are 4MB in size each..in case that matters.
