Like i said im a beginner slackliner that want to get more intermediate. I have been walking on a normal 15 meter 50mm gibbon clasic line. I am thinking about getting a 30 or 40 meter line. I found this website https://slack-mountain.com/en/ . They have a 30 meter kit https://slack-mountain.com/en/slackline-beginner-kit/34-kit-inuit-30-m.html and a 40 meter kit https://slack-mountain.com/en/slackline-beginner-kit/181-pack-click-40-m.html. Both of these lines are 25mm thic witch i am not used to. I am woundering if this is going to be very hard getting used to or if its possible to get a line that is 30 meter but 50mm. Also what is the diffrence between using carabine hooks for attaching it and the normal mechanism that you fint on the beginner lines?

Sorry if my English isnt perfect :)

Im also open for other sugestions :)
