Hello dear Spider-Slackline-Team, I would like to know, what the better choice primitive or the fly long line (50m)? I have a 15 m long and 50 mm wide line. I started this year, but progressing fastly. I usually go alone for slacklining. So what's the better system for me? I also asking because the huge price difference of 70 Euro. Moreover I would like to know if I can get any discount because I am still studying. I would be very happy to get a response:). Have a nice day, Tim
