the CE2 is just like any other cartomizer (diameter).
get one, try it out, if you like it,cut some slots vertically, and your off!
if you dont like how it hits, there is no point in using a CE2.
some people dont like the hit/taste of the CE2, thats why we have these tanks that cater to other types of cartos.
i personally like the CE2 and thats why i have kept my MAP tank, and dont feel the need to use these other types.
