Dear hangers,

I am a rookie, that's no news, and I'm struggling. I was determined to use knots for my hammock setup. I have UHMWPE spiderweb huggers from the Dutch and a continuous loop on each side of my hammock. I am using the Becket hitch but unfortunately the knot is not strong and I always wake up with my hammock saggy a little bit. Just a little, but it annoys me. Another problem is that it's difficult to loose the knot. Maybe I'm just not the kind of person for knots. Is there any simple and ultralight (if possible) solution for people like me (hopeless people)?
I am located in central Europe, the offer here is not as good as in the US, but I'm willing to make an over-ocean order, if necessary.
Thanks!
