i can testify it. the chamber and chimney are identical. the base only differs if you got the wide juice channels version from tobeco (the other version has narrow and superficial channels). the new 12113 has wide channels but they are rounded. my tobeco channels are even wider, deeper and squared.
i think the tobeco is airier than the 12113.
in both of them, a o-ring is needed to help sealing the chimney, between the chamber and the chimney or into the top cap groove. this way, no more leaking here.
less cotton is needed than in those kf with the taller chamber.
i'm very happy with both now, near to the golden kayfun and not lower than the new v2. i'm enjoying the same all them
Haku, glad you have 12113 working well for you .. I still have to get that golden kayfun too. I've been distracted by all the new mods dropping left and right.
