Was having clogging issues so I thought I'd replace and get the mythically good capricorn tubes. This is a good sign that I needed to.

With direct drive, I would say it doesn't make a difference.

For bowden there is a benefit.

I also think that direct drive is superior to Bowden setups in nearly every situation. The current generation like the Orbiter v3 is a very light direct-drive extruder.

There is not. I can empirically prove it to you as well. Half of the 'capricorn' tubing you get from Amazon isn't even genuine - yet everyone there is clamoring on about how it made a difference.

Turns out, that confirmation bias and placebo effect share a lot of overlap. I get it, nobody wants to admit they've been bamboozled. But hey...stay critical of your observations.

Go the other way and buy 3mm tubing and see what it does :)

Fair enough bowden has a lot of issues like filament compression (which can't be fixed with tubing) making it difficult to maintain a steady flow when conditions aren't steady (e.g. acceleration and so on).

With larger diameter tubes the issue of filament compressing gets worse. In a nutshell, a larger tube diameter for "rigid" materials somewhat is similar to the effect of a softer filament/material.
