The control that caught a lot of people out was control 16. The best route choice from 15 involved running down the open hillside to the south west of the control attacking off the statue (man made object) up the clearing to the west. The temptation was to follow the track beside the stream to the south east and attempt to head up the steep hillside to the control. Jonty fell for this and lost a lot of time on that leg. Conversely, the leg from 16 to 17 probably was fastest going straight. I headed down the steep hillside to the north, reaching the track just before the bridge over the stream and then ran south-east up the track about 100m to where a re-entrant made the opposite hillside more climbable. The downwards part of the route would have been the fastest but it looks like I didn't gain anything from my deviation up the track and should have just tackled the hill face on.
