Just got a zmax 2 last night. So far figured most things out. My first apv. It says ego threading but no threads? My tabac bcc's wouldnt fit but my evod bcc's do but no threads? I seen a comment that you can put evod inside cone and will work? Will a 510 to ego work with this for tabacs? Thanks for any help. That said, My vivi nova rocked on it. Great hit and flavor I didnt get out of ego t batts.
