This is probably one of my favorite hobbies and I was wondering if anyone else here on GH is a slackliner. Right now I've got 4 lines.
Pretty standard 1in primitive line for walking and a bit of surfing
Webbing: 100ft of 1in Bluewater climb spec tubular webbing the anchors are Bluewater 1in military spec webbing
Hardware: 3 rocklocks, 1 camp locking oval, 2 omega pacific rappel rings
Probably my current favorite line it is a very portable super primitive line that is perfect for walking and balance training
Webbing: 80ft of 9/16in Bluewater climb spec tubular webbing
Hardware: 1 SMC rappel ring, 1 wiregate neutrino
Gibbon Surfline I use this for jumps and other tricks
Webbing: 100ft of 2in webbing from gibbon
Hardware: Gibbon Ratchet
My last line is a beaten up gibbon classic red that I haven't used in a long time, I don't really like it much and I don't have any pictures of it.
