slackline

I want to learn slacklining

Walking to start with then progress to unicycle across.

Where do I start ?

What length slackline would you buy ?

What make slackline would you ?

Has anyone made or bought a frame, I was thinking something like this ?

15m is usually the best place to start. The setup you posted looks fine and gibbon slacklines are very good. I much prefer to use trees as anchors because they feel more sturdy.
