As promised here is a side by side pic. As you can see it looks bang on. I found it really difficult to taste much difference between the two. I think the commercial brew has a bit better/ bigger body or mouth feel. I might increase mash temp a degree or two next time however the home brew is still phenomenal and I certainly count it as a 'goto' ipa recipe for me.
Mine on the left. Green Flash on the right.
So here is the recipe I used. Note that I used Carastan 30/37, not Crystal 30 listed in the beersmith output.:
