LR tank atty is not much hotter than a normal tank atty. I do not reccommend you invest in a LR tank atomiser for heat. It's too long so by the time it gets to you it's too cool and really no different to a normal one. It's more vapour, NOT more heat for tank atties only because they're so long.
No dual coil I've used on an ego has worked for the exception of the ego dc from madvapes and it is a very cool vape, about the equivalent of a 3ohm cartomiser on an ego. The ego just doesn't have the power to run a dcc. It's pitiful wet vapour that's just awful to inhale. I wouldn't reccommend these to an ego user. Maybe I've just extremely bad luck but 8 dccs not working with my ego is proof enough to me they're not gonna work on an ego.
Clearomisers are great for heat but unless you're up for taking it apart, dealing with it leaking, modding it and making tubes for them yourself they are by far more hassle than a cartomiser. If you're up for the hassle they are pretty amazing for dripping on and if you cut the inner tube they will wick no problem but leaking has always been an issue with them for me.
Cartomisers are most definately the way to go.
Btw, a halo g6 cartomiser is a kr808d-1 threaded cartomiser, volt cartomisers are I think cheaper and pretty much the same. You can use a 510 - 901 adapter (yes, 901 allows a 808 cartomiser on it) from liberty flights or any supplier selling them and use a g6/volt cartomiser on your ego. I do the exact same thing, and this way you only buy one set of cartomisers not two and save yourself some money you would have wasted on a LR tank that does nothing extra in terms of heat or a 510 cartomiser you don't actually need to have seperately if you're buying 808s too.

$3.19 for a simple adapter to use cartos you know you like with your ego or $17 for a new atomiser that wont be hotter. I know what I'd do
Keep savin' and keep vapin' bruh.
