I've been learning to skid over the past couple of months. Running 46/17 ratio. I have never needed to go balls to stem. I honestly don't need to get out of the saddle. Maybe because I have a fair amount or saddle to bar drop so I already have leverage. But if I am going fast I will get out of the saddle and that allows me to skip stop since the back wheel can come up.
I've just started to scratch the surface on track stands. I really want to learn this because I ride traffic with lots of red lights and need to stop and start. I can only last 2-3 seconds. Mostly because I'm in clipless pedals and I get freaked out quickly about going down and not being able to unclip fast enough.
