"WAN" YMBT is well known as a ONE WAY STRIP. T/OFF to the NTH land to the STH. The ERSA doesn't say as much but does mention T/OFF from RWY 14 not permitted due steep terrain. That statement makes my first obvious! If the strip does have an unacceptable tailwind component then simply don't land there. You've got away with it so far, best leave it at that! Besides flying low over the town (any town for that matter) isn't good airmanship in the first place.
