A Gold Line River will beat in quickly to understable goodness. An Opto River will beat in more slowly, but will get there.
Likewise, a Gold Line Fury starts out stable-to-understable, then gets more understable relatively quickly.
Buy two, use one for a week/month, then the other. That's not cycling, but rotating so that if you lose one, the other is in the same general condition while you get a new one to become the new backup.
That is, buy two Furys or Rivers. You're right that a Champ RR would take forever to season in a backup...
