you sure one on one gives you that many pops on its own?
I have never really done 1 on 1 extensively so I wouldnt know. that just make JS training seem redundant when DR along give you 5 off itself compare to whole season of JS may give you 6-7 + maybe 1 pop in Jr or HA.
but Od probably will only give you OD pop since those secondaries pops are usually high sub level ready to pop already. same with the other 1 pos training., that may have changed with the new system but then you probably would be able to get 1 pop per 2 week or so anymore then.
