The eGo is 3.3-3.4V, not 3.7V. The Boge 2.0ohm carto are def the most popular carto and paired with an acorn tank would be a nice setup.
I agree though too about the smoktech tank from CCV. It's a cheap tank and it works really well. It does come with a 1.5ohm dual coil, but personally I think dual coil cartos are only good on PVs in the 4-5V range. Also that low of an ohm puts alot of stress on the eGo MOSFET and can fry it, so personally I wouldn't use it. CCV also sells prepunched Ressurector cartos for a good price. They have the metal base on them to use with the smoktech tanks. You don't necessarily need to use a carto with the metal base, but it does stop the tank from sliding down which is nice. Normally I don't recommend using anything lower than 2.0ohm for an eGo, but I think the Ressurectors will be okay. They do stress the eGo MOSFET, but not like 1.5ohm cartos do. I know quite a few people that use the Ressurectors on an eGo and have never had a problem, but at the same time my buddy fried his eGo two weeks ago using a Ressuector, so that's up to you. I think as long as you dont chainvape and let the MOSFET get hot, you'll be okay using the Ressurectors. They work great in a tank and produce a ton of vapor. I use the 3.5ml smoktech tank on an Epower with a Ressurector in it and it works and looks great. Personally I don't like the bigger 5-6ml tanks on eGo, Epower, kGo size PVs bc it looks funny and makes it really top heavy. The 3.5ml tank looks nice and doesn't look weird. Even with the smaller 3.5ml tank, I still only have to fill it in the morning and I'm easily good all day. I think the 3.5ml tank is perfect for eGo sized PVs, but that's up to you if you want a bigger, fatter one. The 3.5ml tank is about the same diameter as the battery tube so it looks good and doesn't make it really topheavy like the bigger ones.
I would get a 3.5ml tank from CCV and a 15-pack of prepunched Ressurectors and you'll have a really nice set up for cheap. Also if you don't have any already, I recommend getting one or 2 of the Big-Belly drip tips. They look great and fit really snug so they don't wiggle around. Also those drip tips are slightly wider than the carto so they are good on carto tanks bc they stop the tank from sliding up. With the metal base cartos and a big belly drip tip, the tank won't be able to slide up or down so you don't have to worry about it sliding and then leaking. That's what I use on my Epower and it looks great. I think I have every color of the big belly drip tips bc I like them so much and they work so well on tanks, regular cartos, or for dripping, and their comfortable on your lips. You can get them from CCV too to complete the tank setup
