They compliment each other pretty nicely.
Here in OR I had to retire my webbing and carabiners for the winter, and learning trackstand tricks is a pretty adequate replacement. Just came across the thread with people talking about how long it took them to learn trackstands and was pretty surprised. I was doing no handers and 1 foot on the front wheel in my first week riding fixed.
My slacklining buddy was working on a no-hander after 15 mins on my bike (granted he also rides a unicycle).
Anyone else in here slackline? Or have a balance based activity to recommend?
C/N I love balancing on stuff.
