Deffo Kirroughtree black
Glentress and Innerliethen are one stane, although even if they were 2 they’d each have more than any of the other stanes.
Easy enough even in late december to fit in for eg inners xc, GT red with black bits and a play on the freeride park as the light goes
You’d still have GT black/inners DH runs for abnother visit to mix/match into
If north shore style skinnies and whatnot then if its still standing then Mabies Kona Dark Side plus the XC and a play on the 4X
If you want to mix in some DH runs with a 7stane XC trail, then Ae?
Else Dalbaettie for the 3rd
Seomthing like that. Glentrool/Newcastleton(even with Kielder) I’d maybe save for another time If you’re trying to do a 3 best of type trip
If you’ve to fit travel into the 3 days timing can start to make things harder IMO/IME. Also depending how far you’ve to come from
Kirroughtree/Dalbaettie/Mabie/Ae aren’t thaaat far from one abother with GT//inners that much further over Scotland.
