Lol it can't get any worse haha.. I'm in no rush to bin this so will defo see how it changes over a week or so, and tbh I don't have the time this week to make a different batch anyway. I might try cold steeping next time seeing as you are finding that is nicer product at the end, although I'm not sure about using chinook hops.. I might try something a bit lighter like a hallertauer or something
I think hop variety is a key parameter; I've seen suggestions that low alpha varieties are better and obviously I wouldn't expect good results with anything you wouldn't use as an aroma hop.
I'd guess something like Chinook has a bit too much of a pine / spice character. Citra seems to be working ok; I've seen a few examples of people using Amarillo or Lemondrop hops. I have some spare Amarillo so will give that a try at some point.
