hello brunal,
i just found this video,
MistBusters- Super Ultra B.A. eGo Mega Cart Mod Awesomeness, on YouTube for modding a eGo mega/type A cylinder cartridge, and it looks as if it solves a lot of problems that the eGo mega cartriges have all at once - except the problem of a super simple cart
mod.
it's got a straw with a "v" knotch so it's both fast to top off (relieves positive air pressure under the drips) and wicks well (relieves negative air pressure allowing faster wicking); the straw is centered, so if it gets full of fluid it'll drip onto the wire mesh on the bridge; it's got lots of fluval to hold liquid and prevent excessive flow (but there may still be a need to be mindful of which direction the cartridge is pointing depending on how much fluid is in the cartridge); and it's got two wicks - the fluval and the tea bag wrapped around the straw. it couldn't be more complicated except for denser material near the edges of the cartridge opening, which may be why he packs the fluval around the opening of the cartridge the way he does.
my first PV is my ProtoPype, and even though I own two Joye eGo batts and one eGo in-line batt, i find myself preferring the ProtoPype with the eGo Mega/Type A cylinder system (silica wick removed from the atomizer [how's that damn thing supposed to get wet when it's located under the bridge?])... point being that i'm holding the reason i know he's a good craftsman, so if he likes this eGo mega cart mod, i think i'll like it, so i'm going to try it (my Tasty Vapors deserve something better than what the polyester and silica deliver). i feel like i'm getting a bit bipolar now, better quit writing and vape a little more.
