I was lucky to see this act at EJC 2017 Lublin open stage, I haven't actually seen a slackline routine at a open stage before. Just add a contact ball and you have something a little bit special!
Recorded on friday 13 of oct. Is this oldschool? Anyway it is not the hard stuff when using a hand-rail. Just used my small old trainingballs but the movement is clean. hope u like it!
