I have now used the Hot Head Ale yeast on two batches, both of which fermented heavy and fast. I got both from NB, and they had production dates of less than one month before I pitched them.
The first was a Blazing World clone, which fermented from OG=1.066 to FG=1.010 in 4 days. The other was a Pliny the Elder clone, with almost the same fermentation rate. Both were fermented at 68-72F.
This is now my #1 yeast choice.
