Make sure you know how hard you can turn on your bike so you don't strike. I don't know how long your cranks are but I've had problems with pedal strike with some fairly long crank arms and I've been bucked off a few times. Riding fixed has completely changed my pedaling style, it's much more efficient to put force on the cranks on the top and bottom of each crank as well as pull up on the upswing. It helps bouncing when spinning out too. You'll love it as soon as you get used to it.
