Hiya y'all. I don't use too many cartos but I've recently fallen in love with the eGo Mega cartos....but I hate they're not available in silver. I found the XXXXL dual coils but I'm hesitant to order them because I really hate the plastic whistle tips that were on them the last time I used them. Does anyone know if any of the different driptips out there will fit on these XXXXL Dual coils? (I'm talking about the 4.5ml versions) With there being several different size driptips out there, I'm hoping one of them will fit these monsters. Any help?
