Let's try again: Fermentation?

I brewed a pretty huge Barleywine 18 days ago. SG of 1.123. Anyway, after I let primary fermentation subside, I figured I'd rack to another big carboy and repitch w/ champagne yeast to finish her off. I didn't take any SG readings, but I figured, with a 1.123 starting gravity (according to promash), the champagne yeast would still have some stuff to chew on. So, I did just that, over the weekend. 3 days later, there is no acitivity whatsoever. Thoughts?

Champagne yeast takes a bit to get going. You probably could have pitched both yeasts at the same time with no ill effects. Take a gravity reading.
