Tried neat again, but this time let it breathe about 15, then 30, minutes first. Sold on that! Bumps up the sweetness (right off the bat as well as throughout), vanilla, and total score for me. Less thin mouthfeel, the oiliness remains, and the spice I liked when tasted neat (as opposed to over ice, which weakened that significantly) is there; slightly less concentrated, but only slightly. https://www.mashed.com/187313/why-you-need-to-let-your-whiskey-breathe/
