Key Kegs and pillowy carbonation

[Braindead]

1. Has anyone tried using Key Kegs yet, my local Tap room has asked me to keg a few beers for him (secretly) but not sure if corny kegs would work.

2. pillowy carbonation
Ive pretty much nailed NEIPA but to take it too that next level I need the pillowy carbonation. Drank Verdants Dont Tell Gus and the carbonation was unreal, felt like little miniature fine bubbles in the mouth, completely different than normal carbonation... Any ideas how?

0.5 micron air stone?

Natural carbonation instead of force carbing?

It’s not a term I’ve come across until now and had to google it!
