It is not the capacity IMO to drive the need for bigger pods for the Breeze 2 / Spryte / Nautilus AIO; as tootle puffer mostly, the drop-in coil atomisers we use more - are two milliliters of capacity as standard, and they were so before the TPD date in Europe.
Fact is, I noted the standard size for Aspire pods - do wick the coil with
e-liquid much better, more uniformly, without dry hits, and without any vacuum lock.
The two milliliters pods size would be fine, as I said above - most of my tanks are two milliliters;
but they were born that size, and not shrunk afterwards.
