Most aggressive yeast you know about?

[Biobrewer]

I've used Dry Belgian Ale from The Yeast Bay on a high og (1.12) brew, it ate all, almost fg 1.005.

Dry Belgian Ale is definitely the yeast for fast fermentations of high gravity wort. Our Northeastern Abbey is quite fast too, though we've never used it for higher gravity fermentations.

I was quite surprised to see the Crossmyloof Real Ale yeast start fermenting after about 20 mins (fermentation temp was about 23C. I also simply sprinkled it on the wort rather than re-hydrating). It fermented to 80% attenuation
