Pulling Myself Forward to See Which Line Is the Stiffest

The video gracefully skips the discussion of pros and cons, and also technical details of the new lines.

Pros: Stiffer, more visible (red color), less dangerous (doesn't cut into skin as easily), easier and nicer feel (thicker line is just easier and softer to grip), and a more slippery surface (so it isn't worn down as easily, less likely to fray).

Cons: More expensive (I paid 72 EUR for 100 m), more line buildup on the spools (this can affect accuracy of the machine).

Technical details:
Fibers:  Dyneema® SK99. Stiffest there is.

Fibers comparison:
The FireLine uses some type of dyneema, I don't know exactly which. FireLine is micro-fused instead of braided, which gives it superior stiffness compared to its thickness.

The Garda does not look micro-fused. It is braided. I'm surprised by how it can stilll be this stiff since all other braided lines I've tested in the past have flexed a lot. The braid itself has simply been compressible in a way that adds flex. If I would braid three strands of FireLine 0.5, I would expect to add some flex by doing that although strength would increase threefold.

Yet, somehow, the braided Garda line is insanely stiff. Robline does some trick to achieve this, maybe they pre-stretch it to squeeze out the air. I don't know, I'm not a line fiber expert (yet). If you know something about this, please share int he comments!
