Well, I don't get anyway near enough time to keep up with all the threads on the Forum these days.. so if I miss things from posts you've made in other threads, I aplogise in advance!
I'm not familiar with what atties or PV's you've tried already? So I will just post my personal thoughts on some of the devices mentioned.. Hopefully there's still a few options open for you to try?
The standard Tornado Tank is certainly one of them. I agree totally with Tara that Taste Buds and product recommendations are all relative and have to be read with caution. I tend to just post what I think (Good or bad) then others come and do the same, and eventually, the OP can read the thread and make their own mind up? I think that's the only way to be honest?!
I liked the T Tank but never got more than two weeks out of an attie, found the flavour muted and also thought they were a bit too pricey.. but they worked well enough for me to go a good few months or so using them.
The Ego C I personally (and agree with lettie) thought the flavour to be significantly better than the standard Tanks BUT I'm one whose gone from loving it initially, to having lots of Attie issues further on down the road.. which is where I see you're at right now. TBH.. I'm finding them a right pain in the A*s* at the moment!
(Great when they work though)
Finally.. there's all manner of Cartos as you will know. I haven't looked back since I switched to DCT's and CE'2 Ultimates.. best of the lot imo? and if all else fails.. DDing with a 5/901 is still a pleasure for me, though not when convenience or portability are required?..
hmm.. it's a fickle and funny old game this Vaping Lark!
Hope you can find a workable solution!
