I used the one on the right and the 19mm tank and it looks good.If you don't have one of the below eGo cone cover/sleeves already, I recommend find one. It will cosmetically hide the connection gap between the tank and battery, and offers some additional support to the slightly larger tank. Sorry, don't have a link. Ocelot knows where to get black ones, as the second pick of the IBTanked is hers.
