Yay for me, damn that was the easiest thing ever. I was nervous as hell leading up to it. I have about 6000km experience, but hadnt practiced full lock turns until last nite. Good thing i went out last night to practice, poor boots took a licking, but it was actually fun to see how low and tight i could get.
Tips(if thats what these are), ride the rear brake like nobodies business, and ride it hard. I was given 3.5 "stalls" for a u-turn, and i practiced it until i was just inside 2. If you can do super tight circles your set.
