lean back abit, turn the bars the way you want to go (remember it's opposite to how you'd normally turn) and look over you're shoulder. Until you become more used to the feeling it's going to feel pretty goofy. Smoothness comes with time. Also, try going abit faster. It's pretty hard with no momentum. I found it easier learning how by 180ing first, rather then pushing off something.
Had a pretty decent ride today, messed around in the local skate park, rode some dirt jumps, went scouting for a new dj spot (unsuccessful), and rode some street.
Those KHE dirt's are pretty bloody good. Roll very smoothly, grips better on concrete than the schwalbes, and worse in the dirt, which was expected. Very happy so far.
Side note, the info on crc is wrong. The max pressure for the 26" tyres is 85, not 120. That's for 20".
