I recently converted too, using LOOK pedals. First fall was in front of my house since the road is on a bit of an incline and I couldn't push down on the pedal and pull up fast enough to get enough momentum. Slow yelling fall to the left side, lol. I made sure my body took the brunt of it to not scratch the bike.

Second time was at a light. I thought I had it timed right then the left hand turn signal goes on and I can't go through!! Luckily my buddy was in front of me so I sorta fell on him with my right hand. Had he not been there I would've fallen flat on one of my sides, that would've been fricking embarrassing.
