Ah, that's going to be a problem. I appear to have mislaid all my midichlirans :/

I'm trying to picture the tomahawk and all I can figure is: you're going forwards fast, right? Then you do a 180, so you're go backwards, just as fast. Then you take the weight off your wheels and put it on your stops.
Result: your head is going a lot faster than your feet. How are you not always going to fall flat on your ass? It's physics! XD
I'll definitely have to look up some videos! I'm intrigued!
