I've been using all types of attys and cartos with 2 Vari's and haven't had a problem with threads at all.
the Vari threads are super tough... I've seen that one person posted a problem but chances are better you won't need to...
the Fusion is worth it to get the adapter for the Vari... I asked the same question and also got some gold V2's coming because all the raves... (a 510). I go by trusted vets here. in this case 5card says they're the best at 3.7 to 4.+v; believe it.
I am not a carto guy... been dripping 100% since i got my vari's - for 6 months.... as far as cartos go, the Fusion could be the very best even over the DC's... and certainly those troublesome CE2's and G4's.... imo.
Some really like Tanks on the Vari... i never got to those...
I always tell folks to never diminish the value of dripping experience... it all adds up and eventually after going through all the bottom feeders, the vape mate, etc, I still insist there is no more pure way to get a juice vaped... it all depends on dripping skills... juice type, pg/vg, resistance, watts/volts, drip tips (PYREX is the ultimate).
the Iken 306's are good... the 3.5 will probably last longer and you'll vape at the high volt ranges of the Vari. the 2.0 is good too at the lower ranges up to 4.+ v.
While 306's are great to most, I prefer a standard atty (510 reg 2.2 Ohm, or dse 901 2.8 Ohm reg - at anywhere from 3.6 to 4.5v).
But the 306 is great for pure vape and surefire vaping success.
I am using a Fusion now on one of my Vari's; haven't really figured the best way to refill; like when and how much... I use a bottle with a needle setup (racers-edge.com) so I can get it down the sides.
I hate the idea of burning a carto; carcinogens, and the flavor degradation ... and then it's tainted for good.
Use more pg for carto's and watch out for thick dark juices.
Been reading this thread because I want to use IKV on my Provari thats coming tomorrow. I figured I could shoot a question here for all you pros since its already an IKV and Provari thread.
I have some 510 mega cartos on the way...are there any other cartos that taste better? I used the Fusions on my 801 threaded PV and were great, but can't see how much better they can be taste than the 510 megas I have en route. Have to use the adapter also..worth it?
Also...I want some IKV 306s! They just seem to be phenomenal. However, I see they are 3.5 and 2.0 ohms. Since the provari is VV does it matter which I buy since I can basically adjust it to the same setting with voltage? Any experiences with one being a bit better than the other?
I am definitely prepared to use some sand paper to smooth the threads down if any don't fit on the provari.
Thanks for info here...trying to complete the perfect vaping setup with my Provari.
