I've heard that some folks take that comment to the extreme when it comes to back ups. Not me, but some folks do.
While it could be said that the only time a Reo might need a back up is when a hoople gets their hands on it, I don't know how anyone could get by with just 2 Reos in their daily rotation. We have two hands, that means with only two Reos you don't have a back up.
Which one for #3 delivered by Friday should be your personal choice though. So I'll not recommend which one that might also make me appear to be enabler.
