Prusament PLA Blends are to viscose for standard PLA profiles? Maybe linear advance callibration is needed?

Hello everyone,

I bought these two filaments:
https://shop.prusa3d.com/en/prusament/1213-prusament-pla-royal-blue-blend-9kg.html
https://shop.prusa3d.com/en/prusament/1420-prusament-pla-viva-la-bronze-blend-970g.html
My issue is probably mostly its viscosity, because when I try to extrude it is not creating standard string of filament but more like thick blob line. I tried different temperatures but even with temperature tower I did not get any better outcome and it is much more brittle than any PLA.
It is mostly seen in top layer, it is full of holes around edges, because it releases pressure to early (belts are tensioned properly and top layer is set to speed of 20 mm/s). Increasing extrusion results in overextrusion in other parts of print. Even on sides of print it looks like problems with linear advance.
Do you have any tips, what should I test, or what can be my issue?
I tried linear advance guide on this web, but for Mini+ there is only mentioned it is well calibrated and will not be needed and when I tried gcode for mark3 it didn't end well. It did not trigger auto bed leveling and I had to manualy compensate at least 150 microns to get at least some print, but still ended with just mess.
Thanks for any ideas and have a nice day 🙂

What profile did you use?  Suggest you switch to Prusament PLA profile in slicer

I am using Prusa PLA profile for filament and print setting is 0.20mm QUALITY @MINI.

Here is example of issue. It is default gcode what was on USB drive with Mini and there are visible holes in gold one.
In fillament swap foto is diferent viscosity of that PLA.
