@walldoggy: Thanks. Yeah, I use it quite a bit when the other team is blindly streaming towards B from A from the Dirt Ramp or Wooden Bridge, they are expecting the hit when they round the corner near the White Truck but not before they get there.
To reach that spot, just run down at the Ditch towards A and where it splits to go down the Ditch or up the High Street you can jump and run along that verrrry narrow ridge all the way up to the Wooden Bridge.
