Personally I think 30 IBU at 60 is a bit much. You can get more complex flavors by adding more hops throughout the boil.
A lot of people here have been skipping the 60 min addition with good success. I finally tried it with my last all Citra neipa and the bitterness is still there, but it's much softer. 30 min addition 15ish IBU, 15 min addition 9ish IBU, 5 min addition 7ish IBU. HUGE WP at 180 for 20 min 30ish IBU. All IBU calculated via Beersmith so take that how you want. BS says I'm getting 60.8 IBU total. It's definitely not a bitter bomb. Super soft and balanced. Loving it so far.
