Terrible Ale

Unibroue's Terrible:

Just a shade or so darker than Westmalle Dubbel. Huge, spritzy, perky, appley nose. Kind of like Affligem Dubbel but a little darker and faintly roasty. Gotta have a little carafa, lots of special B. Some Caramunich, something toasty like Biscuit?

Here's an arbitrary grain bill just for fun:

11 lbs Belgian Pale Ale Malt
1 lb Biscuit
1 lb Caramunich
.5 lbs Special B
2 oz Carafa II
2 lbs Beet Sugar

Key to this beer would be a really, really fruity yeast--Chimay-ish? Or the Wyeast Franco-Canadian yeast? Bitterness for this is mild. Probably only like 40 IBU's and practically no aroma hops.
