You know you want more than a primitive slackline kit. You want all of the cool little goodies. You hate hassling with cumbersome setups when you should be having fun. You want a flexible setup, from super low tight lines, to a longer or looser line. You realize slackline kits aren't magic; they all tighten webbing, some easier than others. You want the freedom of being able to set a full length line by yourself or set it as short as you want without tying knots in your main line. You want it to be incredibly easy to setup and have it cost about the same or less than making your own dedicated primitive setup. You aren't worried about practicing your rigging skills with lots of expensive equipment - you just want to have fun.
If that describes you then here's the kit you need.
