The only reason I can see for keeping the RoV is as a backup, but if you don't need a backup you might as well get something cool for it.
Out of all the Orange's I've owned the AD30 is the only one I'd consider buying again. It was a sweet ass amplifier with a unique tone that felt great to play.
If I could find one I'd prefer the AD30R (single channel w/ reverb). I never found the dual channel setup particularly useful since the amp amp lacks the headroom to have anything resembling a clean channel, so I wound up with a darker crunch and a brighter crunch... the nuances of which disappeared the second the drummer hit his snare.
