I haven’t brewed it yet, it’s on my list. I made a similar beer NEIPA style, it had similar grain bill and yeast and some higher dose of different hops and it was great. When I whirlpool, I typically go with 170 degrees for 20 mins. You shouldn’t see too strong bitterness if you use all late hopping and whirlpool hops. This should come out around 45 IBUs. Let me know how it works out. Should be good. With the London Ale and oats, it should have a nice mouthfeel which helps with the hops. You may also want to add some gypsum which will help accent the hops.
