Might reach out to Steve and ask him for some clarification on this one, Stan Hunter said on the Discord that Steve may of said it was harder than Dreamtime (pre break) (8B+) , maybe @TdG or @remus might know him better?
Also it seems Gus went with mid 8B+ on UKC.
Good shout, I haven't got any contact details so you'll be as likely as me to get him via insta or whatever. Might be able to track down some details via friends if you don't have any luck.
Given how long it's gone without a repeat it does feel like it could be a candidate for an upgrade, will be interesting to see what Steve says.
