IME its best to start with the regular sized stems. I know some people like the shorty, bit you can easily achieve a shorter bowl by using domed screens. Buy a shorty and you can't ever make the bowl bigger
Soak stems in ISO and store for a future QWISO batch.
Soak stems in scalded milk and make hot chocolate.
What if i want to put a domed screen in a shorty to make it even smaller? The Solo stock stems have a bigger bowl than my WW stems and i wouldn't mind that option.
I would keep both if i worked at Planet Vape.
