I realize this whole topic will be subjective, but I'm just in the process of receiving my Kato Box mechanical mod. After watching a few Youtube videos it was suggested that a longer drip tip be used. I'm just not sure how long it should be. I've seen a few 70mm drip tips but they seem too long or more for hammer type pipe mods. Anyone have any experience with the kato? Drip tip size or material recomendations?
