what knot doesn't slide?

[JaxHiker]

I used a knot bone on one end, and fig 9 on the other so no knots here.

Maybe it's me but I found the knot bone a heck of a lot slower than the figure 9. I love my figure 9s.

I use the small carabiner and figure nine combo. That said, I also like the clove hitch and taut line hitch.

I'd go figure 9's but after spending the $$$ for sil, 1.1, down, and all the cord, I don't want to order more stuff. I want to use just the rope.

What about this way... you won't 'hurt' any tree ;-)

This is called a FLEMISH FLAT KNOT (Belgium)

here's an idea. prussik a loop onto your ridgeline, then you can use it as a pulley/truckers hitch and tie off with a slippery half hitch. then the only knot you'd use is the slippery, one on each end.

My concern with this setup is that Figure 8's (another, more common name for this knot) have a very low "rolling weight." What that means is if you were to clip above the Figure 8 like suggested, a sharp tug caused by a gust of wind or something may cause the knot to roll down the line. While it won't come undone, you just lost a bit of tautness in your setup, which could then create more problems in the windy weather you are experiencing. (Granted, this isn't terribly likely, I'd rather be safe then sorry.) I'd recommend creating all of those knots with loops at each point, and then clipping your ridgeline to the loop, so it's working with the knot. Another knot that could work for this are Alpine Butterfly's.

An easier knot to get that non slip V: use a marlin spike hitch...just put the toggle in the line where you want it and then the end loop "on the knot, not the toggle." I do that on one end and a figure 9 on a prussic to do my adjusting at the other end.
