115 lbs? dang, eat a cheeseburger. Male or female?
I'd chime in on the skidding part, buuuut... I've had my fixed gear for a couple months and have never attempted a single skid. I just like riding really, really fast. If I'm on my bike I don't feel like wasting time dicking around and not just pedaling hard. But, that's just me. I'll probably start trying some of this when I get more time to ride.
