As you may remember, I mentioned quite early on, that I personally prefer rougher meshes as they can store more substance, have a lower resistance, and better mechanical stability. The big drawback with rougher meshes is the higher thermal mass, so it needs a bit longer to heat up (not relevant) and quite longer to cool down again (relevant if you vape a substance not all at once).

But the big thermal mass can also be an advantage. E.g. if you vape a lot of a substance at once, and you therefore need a big mesh area, you need a lot of wattage from your mod, so that it can hold the temp when you inhale. The big thermal mass then makes it possible to vape in such a way, also just with a one battery mod.

I usually use meshes around 80-100, for some substances even around 50.

Awaiting eagerly your experiences with the sai.
