What style of vaping? MTL or subohm direct lung? Either way, the VCMT is made in 25 and 30mm versions. I don't have one, but they tell me it's a super tank with a huge deck. FWIW, I don't have any trouble fitting complex coils builds in my Indulgence MTs or my Advken Ωega. All of the tanks I have mentioned are primarily intended for big air subohm work.
