How often do you have to tighten?

I started slacklining a while ago and have found the best tensioning method to be a simple 4 biner one (similar to the one in coldclimb's setup diagrams). However, I have found that I have to tighten frequently with this method. I did not adopt this method until I got some new webbing a couple weeks ago. I am not sure if it is the new webbing stretching, a flaw in my system, or just how it is going to be. How often do you guys have to re-tension your system while you are out?

My line is roughly 40 ft long using blue water climb spec. webbing (feels awesome compared to standard mil spec!)

Thanks

I reckon the system is fine, it'll just be your new webbing stretching - this is normal.

I think with shorter lines that you need to re-tension more often than with bigger lines, because the tension required on a big line seems to overcome the elastic release you get in the lower tension range... although a big line sags far more if get's wet.

Why do you prefer the feel of the climb spec so much more than mil spec?

The only reason I like it better is that it has a softer feel to it than the regular mil spec. I know it has some better wear resistance due to a finer weave, this may account for the softer feel. Not sure if anybody else agrees, but to me, it is definitely better.

I have only used the climb spec webbing from blue water, and a couple different mil specs from various suppliers. The difference is not extreme, but I think it is definitely noticeable.

In the mil-spec vs climb-spec thing, the only real difference is the weave type which while being more abrasion resistant can be more slick when wet and in my experience cause much worse rope burn if you fall against it. I regard it as strictly personal preference, as I prefer mil-spec and mil-spec is cheaper to boot.

There is a strength difference, but it's not much, usually 4,000 lbs to 4,200 lbs for mil-spec vs. 4,500 lbs for climb spec. (i.e. negligable).

Flat webbing however can have radically different handling characteristics as well as strength & elongation differences.



Tensioning, yep, new web will stretch much more than old web. That problem with go away or at least become less of an issue over time. You'll notice that even a little moisture will make a slackline stretch more too.

To each his own: I'll take the abrasion resistance and extra 4kN or strength in climb spec. (22kN vs 18kN for Mil spec).
