I've brewed with the Giga Yeast Vermont IPA. It is a fast fermenter and generated pleasing fruit notes. I'd definitely use it again. It's a bit hard to come by, but you can find it at Oakbarrel Winecraft in Berkeley. see http://www.oakbarrel.com/beermaking/liquid_yeast.shtml I called them up and they sent me a refrigerator pack of the 200b cell pack the same day...
