Anybody can recommend a dyneema line that's not slippery for pigtails?

One of the main properties of UHMWPE is very low surface tension, i.e. slippery.
A line with heavier coating is likely to be less slippery, but can't recommend specific make/model.

I recently got these original Cabrinha pigtails, 2 of which are adjustable, for less than 10USD/set and I'm sorted out with pigtails for next few years. Now I can spend my free time splicing main lines and other stuff.

A blob of Cyanoacrylate glue on a knot in dyneema will stop any slippage.
Just try it. Doesn’t seem to be affected by subsequent water immersion.
Makes it pretty difficult to remove the knot at a later date though.

How does your figure 8 slip - did you try adding simple or double overhand knots? That should stop slippage.

I wanna have multiple knot options so adding another one to hold it isn't an option.

You can have as many knots as you want, without slippage, on the back lines. And do the adjustments there.

For the front lines, adding some kind of stopper knot for the figure 8 should fix the issue of the slippery dyneema.

I have used 3mm dyneema from Marlows, Southern Ropes and Holt without having knot slippage problems. I set the knots with 2 bars one through the loop one with the line wound and half hitched. Stand on one bar and do an appropriate dead lift with the other bar; then cut to length. If you have to pull a bitter end, tape it and use pliers or molegrips to grip and pull it in a way that you do not injure yourself if it slips.

In the past I have occasionally put a few stitches through a knot and you could consider that if your dyneema is particularly slippery, although a well set knot goes pretty hard and is not the easiest thing to stitch. I would not expect to stitch the knots for an ordinary pigtail.

The Holt dyneema I have used has a tacky waxy coating which gives the impression of making a knot set particularly well but i don't think it is a major point. The coating disappears with use.

If you want confidence in your work you can use your full body weight to proof test it as we are talking high working loads for 3mm dyneema.

As an aside and to understand how things are working you may find these questions interesting:

72x diameter is for full load :- is that needed?
If you took an unlocked tail out of the splice would it slip through a loaded larks head?
Is the tail more likely to slip under low load or high load?
