I might give the Splitfire a go after the holidays and see how it vapes myself.Wasnt trying to imply that any of the 'tanks" mentioned in this thread were lesser except maybe in terms of flavor, just wanted to point out that the ones mentioned were actually hybrids and not 'true" carto/tanks.
not really even a hybrid. they're clearos....really big clearos.
to the OP: depends what you like, personally i've been getting more into my RBAs lately, and you can get a cheapo genesis style atty if you've had a few go-arounds with rebuilding your nova and have a superior vape overall, the one i've been using in particular lately is the AGA-T from clouds of vapor.
other than that, i've never been a fan of the vivi nova...i've always found it to be inferior in so many ways that i couldn't look past that i just never cared much for it...the kangers are much of the same story, although i do prefer the kangers if i had a choice since they are bottom fed and don't have issues with dry hits.
as far as cartotanks, i like them much more than the larger clearos....i have a couple of glass tanks from IBTanked as well as a phiniac and enjoy them all equally...
i tend to find that people who don't like cartomizer tanks generally use cartos i've always seemed to find less-than-stellar performance wise, if you decide to get a cartotank, be sure to run over to ikenvape and grab yourself a few 510 platinum series cartos (they also come pre-punched for tanks) as issac simply stocks the best cartomizers around.
