This rda is pretty to look at but the airflow design is stupid. Gonna be drilling some holes but I can't figure out what size chuff to order. I think the total diameter of the top cap is about 26mm, then there's the diameter of the oring section. I lost my Damn tape measure lol. Would I be ordering for total diameter or inner diameter? And doesn't anyone known the specs cuz I can't find the top cap specs online.
