BR715,
Can you tell me where in the VA industrial agreement (if you can call it that) does it mention any sort of progression from the back seat to the right seat. My understanding is that VA has only alluded to S/O's progressing, via DJ and then back again. Even though DJ HR have no official knowledge of this!
I would suggest that any talk of vertical progression from back to front within VA is speculation at best. Logically VA should do just that. But to date they have made no indication of it being a possibility.
