The 19mm wide is perfect for the 25mm bangers (1mm clearance).
I expect 23.5mm would be perfect for the 30’m bangers ... I ordered one of these anyways as they do sound pretty sweet!
Main thing about the 3mm gap is I feel they will “bang around” more than ideal when q-tipping out after your dab. I even find this happens noticeably more with my sapphire insert that is about 18.5mm vs 19mm ... it was noticeable enough that it led me to measure the difference to see if it was all in my head ... it wasn’t
