I have just tried the thinner felt mesh: yes! Betula approves!
This is definitely a step closer to the CO sound.
I can imagine, some hardcore Atrium/Atticus/Eikon fans would prefer the thicker mesh, but for me as someone who is in love with his CO (with thick pads, no mesh), it seems the thinner felt is what I prefer.
I tried the CC without mesh too; it is not completely unlistenable, but certainly becomes imbalanced with too much brightness in the treble.
Regarding the 3 pairs of pads I have at hand, so far it is a tossup between the full leather and the hybrid depending on the music genres. Both pads have advantages and compromises. I am least keen on the full suede pads. These are great for some very mid-centric music but take away too much from bass and treble focus/dynamics.
With my most listened genres I probably lean towards thin mesh/leather pads combo, but it is still early days to proclaim an ultimate winner combination.
Definitely all 3 pairs of pads have a tuning purpose here which I can see, as opposed to the thin pads on the CO which I disliked.
Enjoying the journey so far.
