Been slacklining for almost 12 years and been using the same tensioning setup since the beginning. Two biners in a clove hitch approximately 10 feet from one end (in line, distances will vary depending on line length) running to a single biner on your anchor. Gives you a little 4 to 1 and if your webbing is dressed properly it will lock itself off. If you want to give yourself a little more mechanical advantage you can throw a little prusik cord on there. When walking try to find the line with your toe and walk toe to heel rather than heel to toe, find a fixed point to look at rather than looking down at the line. If its a windy day you can clip a biner or two onto your line to quiet the flutter. I don't like the ratchet strap systems because I've broken them before but I do think they've improved them. And 2 inch webbing is cheating. Real men stick with one inch. I do have to say that I'm pretty amazed at what these kids are capable these days though. I always did it as a rest day activity rather than a sport by itself.
