I'm glad to hear that I'm not the only one that doesn't like the 120. I thought it was pretty undrinkable myself. The 90 tastes way too sweet to me, but I love the 60. I recently went to the DFH pub in Rockville, MD and had a mixed pour of the 90 and the 60 (the call it 75 something) I thought that was outstanding!
I wasn't all that impressed with the 60 min either. I just have had much better IPAs at better prices. It's cool they do wild stuff with their beers, but when it comes to a straight forward IPA, DFH has not impressed me.
