Balance is a horrible term to describe IPAs/IIPAs.... something that these breweries are known for doing very well.
The beauty of a good IPA is really about perfecting unbalance.
Regardless, I'm just saying it's my opinion that Hill Farmstead hasn't perfected that unbalance. It's just my opinion. You're not wrong for yours, either. E.g. their "pale ale" (Edward) is 82 IBUs. It's hard to taste anything but the bitterness in a beer like that. Also, another example, twilight of the idols (a porter), is mostly hop bitterness for me (not enough crystal for the style...at least as far as I could taste).
