Well, brewed this clone up about 8 weeks ago - followed the recipe to the letter. Used Gigayeast Vermont Ale. Was able to get a couple Heady's to taste side-by-side with it. Also sent some of my homebrew to another person who had Heady on hand to taste as well.
Appearance - REALLY close.
Flavor - this was a great beer.... really great. But, it was not the same as "Heady." I felt like there were two significant differences in mine. 1.) Mine finished a bit sweet. My gravity went from 1.075 down to about 1.015-16 and that was where it stayed. I am hoping when I brew it again, I can dry it out a bit more. However, I thought this left mine sweeter and fuller than the real thing.
2.) The hops - I felt like mine was "fruitier" and Heady is sort of ..... I don't know, more assertive I guess. Heady had more of a lingering bitterness I felt like. Not sure if my high finishing gravity/malt sweetness was at play with this as well or not.
As I said - I brewed it about 7-8 weeks ago, and I am sitting here drinking the last glass of it as I type. It is a one I bottled off the keg before it kicked...... 2 weeks ago. I would say this is the best IPA I have ever brewed, even though it was not exactly like Heady. Will be brewing this again for sure. In fact, tomorrow I am basically making a "Heady Junior."
I took the recipe as is, and scaled it down to 1.045 gravity and cut the hops in half. Hoping to get a "pale ale version" of this so I can put down a few pints ...... 7-8%IPA's tend to be filling and sneak up on you

So, seeing if I can scale it down for summer. I will then harvest yeast from the Heady Junior and rebrew the full version.
Great, Great beer. Thanks for all the work by everyone who contributed. Looking forward to rebrewing it and seeing if I can not improve my process a bit and get it closer.
