Anyone who works on #streetart #graffiti or large #acrylicpainting have recommendations for large dabbers or refillable paint markers?

I'm currently using Posca markers for my smaller pieces but want to scale up farther. Looking at 15mm+ tips, like Montana Colors or Liquitex.

I know what's out there, so this isn't #lazymasto. I'd really like any personal recs/prefs.
