I use 30mm clear bottom bangers regularly however, new or low-tolerance fam should use smaller sizes. 710 Coils offer fantastic coils at reasonable prices. I’ve picked up bangers from 710 and Greek Glass and had no issues with either.
Inserts
When I do uptemp/coldstarts I use different inserts depending on the concentrate and what I’m trying to do. I use quartz only and depending on the need I use a “plain” clear, smooth opaque bottom or textured opaque bottom. I have a pile of inserts (mostly from Greek Glass or 710 Coils) and don’t use them often right now.
Carb Caps
I use a Greek Glass bubble cap I ordered along with one of my regular bangers and it’s served me like a true hero for many years.
Dab rigs
I use smaller dab-style rigs for dabbing rather than the typical bong or other smokers glass. I use minimal percolation and rely on recycling or temperature control for settling the harshness (if any) down.
Misc
I thought I should mention that I’ve used a MiniNail dab tool for many years. It’s nearly perfect as a dab tool for me. I don’t use it as a carb cap since I use larger bangers. As with inserts or terp pearls I ended up with a pile of tools of various qualities and most of them get used with extraction or for making noise packed in a box when moved.
