It's a lovely challenge! Went in there a while ago with a SSW wind, 3 up in an Archer. Big trees almost at threshold 27 made the approach interesting. On inspection, 18/36 too boggy to use for departure. 27 has an upslope from halfway point and has a line of trees on south side for first half of runway, giving no headwind - but also causing a drop in the tailwind component round about the rotation point if we'd taken off downhill on 09. But then there's the trees on the climbout from 09. We opted for 27 and managed to outclimb the upslope. Then it's level off at about 500' agl to keep below the Abdn ILS traffic. Exciting stuff.
