I thought I had replied already, but if not - there are only 2 WSO jobs on the P8 vice 3 on the Nimrod. There are/were are loads of WSOp slots on both as well as the WSO seats. Reaper, Voyager and other types fly perfectly well with WSO or WSOp in the seat. I don't see Biggus' point to be honest. The only type that is WSO only is GR4.
