Slide and grip hitch

[SenzuBean]

I was trying to tie a decent slide and grip hitch, and turned to the adjustable grip hitch (tied as a loop). I found its performance lacking - namely that it slipped relatively easily (when tied as a loop). I noticed how it was "failing", and that it was mostly that the knot wasn't very cohesive (the half hitch end of the adjustable grip hitch was not joined to the rest of the knot). I tried to fix that problem by finishing with a and got this knot, which grips much better (at least on this diameter of rope).

Image1: - start of the knot, so far same as adjustable grip hitch (tied as a loop).
Image2: - finish, front of the knot
Image3: - finish, back of the knot.

I got the idea for the adjustable grip hitch from Andy's site: http://www.asiteaboutnothing.net/cr_most-useful-knots.html
So would be interesting if he sees this thread.

Another variation that is probably better still (even after adjusting it, I am able to load the loop much more than the other slide and grip knots I have tied):

Tying is as for the OP knot, just pass the working end under both loops instead of just the second one).

Have you tried Blake's hitch tied as a loop? Works well for me.

   For the slide-and-grip hitches, which are hitches tied around a straight, tensioned main line, see :
   http://storrick.cnc.net/VerticalDevicesPage/Ascender/AscenderKnots.html
   Now, the adjustable loops belong to a different class of knots - because the continuation of the Standing End ( the Standing Part before the tip of the eye ) can be forced to follow a slightly curvilinear path. Within and around such an "obstacle", the task of tying a nub which will not slide easily towards the tip of the eye, becomes a much easier job. ( See the attached pictures, for adjustable loops where the continuation of the Standing End follows a helical path ).
   Therefore, I do not see why we should use a slide-and-grip hitch as nub of an adjustable loop.

Just to be clear - I only tied it as a loop as I have only a single piece of rope at my desk

I will take a look at those loop hitches soon.

This was also my first thought (to suggest ...).
+1 for Heinz Prohaska's (my name "Prohgrip"
[--or have I used "ProGrip", "ProClamp", "ProhClamp"?
("klemmnoten" is a German word for the gripping hitch(es)?)

One issue with the Prohgrip is its need, roughly,
to extend a bit in setting --i.e., on a pulling away
from the gripping coil vs. pulling into it, one wants there
will generally be, or should better be, some opening
of the helix with tension.  This, however, will be some
material lost to the tension of a closed loop formed with
the knot --2 steps forward and a half step back sort
of matter.  Whereas when the gripping coil is loaded
at the away (from pull) end such as is done in the
taut-line hitch, the knot better grips in place;
there is some feed of material of its S.Part as tension
builds and the knot compresses, but the other way
has this also, in addition to extension.

In some quick fiddling, I find the Prohgrip to work
better than the OP's knot, which didn't work so well
(to my surprise).

I will tie some of these knots to see how they go (will probably take a long time hehe, there's a lot of knots). I suspect that the angle of pull will effect which knot grips better.

Bear in mind the number of differences in wrapping turns when judging the knots. The Prohaska looks like it can be tied with fewer, which could be a truer comparison of strength to some of the knots I suggested (or vice versa, add turns to the knots I suggested - maybe they'd get worse).
