o.Ojust cuz tst uses the eraser motion, doesnt make it the same thing...=eraser is just shifting up and down fast to create oversteer to make the car turn.tst is a technique that uses eraser to another lvl, by starting to erase into the turn early, feinting back out and erasering back into the turn, hence the name TST, meaning Tsat serng Tsat, or erase-up-erase.
