OP ...
Since you said that you
don't want to rebuild your coil and wick assembly, but you want something a little bigger than those small 14mm EGO style clearomizers, your choices are a little limited, but there are still choices.
My choice would be to buy a full size (22mm) clearomizer such as the Kanger "Aerotank Mega". Then power it with a 22mm mechanical tube mod or a VV / VW box mod such as an MVP 2.
Here is a photo of my 22mm Kanger Mega setting on top of a 22mm mechanical tube mod .... The Kanger Mega holds 3.8 ml of
juice and has replaceable screw-out / screw-in coils in a variety of ohms ... Nothing to rebuild yourself
