Re. DCT's - if you didn't know already, you need to DIY a much bigger hole on the side of the carto. Once filled (do the carto by dripping in the poly as per usual) fill up the outside tank. Then I leave it to really soak through for hours. Getting it right in the beginning has a big influence on everything after.
I have only dripped for experimentation. That's no use for me, I'm probably quite a heavy vaper so I always use some system that can hold say, 1ml+ of fluid. The conical tanks that go on ego batteries are all well and good but they die off so quickly. After couple days you struggle. The only things that really work for their value, in terms of life and vapour production and wicking problems - I use all the clearomisers. The each have plus and minus points but for the price, you will get days of heavy vapour production before it weakens. Considering they are only about £2 each, if they even last 3 days, that is a bargain in smoking money terms!
Even if just using ego batteries I would still recommend CE2's or CE3's for vapour volume and life. For some people they can be a bit fiddly filling them up so if you have arthritis or something perhaps they would not be good but if you have use of your hands and eyes, then they are fine. A fill lasts a day anyway so it's not like you have to mess around all the time.
I was using ego batteries for around 15months until a friend got a lavatube. I ordered one that week. The standard version takes a long battery that should give 2 full days vaping. I got the shorter version and the battery will last a day, although because it comes with 2, I take a spare charged battery out with me anyway. The batteries are only like £5 each, cheaper in bulk. The charger is a bit bulky, it's not USB either but there are ways round that if it's important.
If you vape, I really cannot see anyone going back once they try a lavatube, or similar quality vapouriser. It's that good, and it looks like a light sabre, which is fine with me.
