so ive been looking through vendors in the west coast area and see that the ego mega atty has 2 different ones. mine for example is a cone shaped mega atty and most vendors carry the cylinder shaped mega atty. i only found one vendor that has the cone shaped atty. even the vendor i bought my kit doesnt have it or i have no clue if they do because their site is unclear. so for those members who have Egos but use the mega atty and not 510 attys or cartomizers. is there a different in sizes when it comes to getting the carts for it. im so confused since when i first started going through and doing my homework on PV's all the Egos started with 510 attys. now there's these mega attys which i have. but like i said. theres cylinder ones and cone shape ones. and theres only one vendor that differenciates the 2. i hope someone can clarify this for me. cuz i dont want to buy the wrong thing or end up buying more. and if there is a difference between the 2. then i might have to look to another vendor for parts and my juice from my original vendor. sigh. sorry to ask this if its been answered. thank you everyone.
