1056, Safale-05, Notty?
The 1056 and more recently the Safale-05 have been my IPA work horses since I started brewing. I had great luck with Ringwood Ale from Wyeast in Yoopers DF Clone.
Any other favorites?
I used Ringwood in my last batch of Yooper's Dogfish head, and it turned out great too. Pacman works wonders, of course. I'm going to do a double batch this time with Pacman in 5 G and Wyeast 1968 London ESB in the other 5 G, just because I have it.
