The search for the perfect juice that satisfies 100% of the time is never ending , the key to vaping is having a variety and switching throughout the day as a single flavor always gets old if you vape it enough.
This is very true. Although it isn't what our wallets / purses want to hear, it is best to have at least three different set ups and juices on the go that you can go to on any one day.
I reckon an ego and evod type set up + a VW/VV and Nautilus type set up + a VW/VV device ands subtank set up is the way to go.
Have different flavours and juice types in each tank. The subtank gives a hot heavy lung hit to stave the hardest of cig cravings, the nautilus for me is perfect for savouring flavour in a relaxing pipe smoking kind of style and the EVOD is good enough for breaks at work for a quick light nic hit and analogue sort of experience for me.
I currently have a fruity creamy dessert flavour in my subtank, heavy VG, very tasty but no good for when I get analogue cravings. Then that gets boring so I have a very dry cigalike RY4 in my nautilus Mini which is good and different enough to be interesting for a few hours once the appetite for the dessert flavour runs out. These two are both zero nic.
Then sometimes like yesterday when I was bored of both, I actually vaped my small ego battery with an evod of 3mg RY4 in it and was happy using it all day, surprised that at that moment I was preferring it to the Nautilus and the subtank.
Also that way you don't have to clean out a tank to change juices, you just go to the other device or like me take a tank off of your VV/VW device and swap a tank with a different juice on to it and then not have to empty the first tank.
I'm not going to lie, I still have a cig or two once a week with a beer or two, but I am smoking way less. And the best way to do that is if your current PV + tank + juice is not doing it for you, to have a couple of others to be able to pick up and fire straight off the bat without cleaning or re-filling etc.
It's a lesson I've been learning during my recent two month return to vaping after a long absence from it.
I wanted to keep it cheap before and only ever had one device and one tank. Most I ever had was one battery with two XL cartos with different juices to swap over.
But now I realise I need at least 3, a small package for work like the evod+ego, A VW PV and a sub ohm tank and a nautilus style tank.
I'd really like in future to have an extra CF4 PV and an extra nautilus mini and an extra subtank so can have 5 juices in rotation. But at the moment 3 is enough. It's all about fitting the right juice to the right tanks and watt / volt / ohm range for the best 'vape' and having more than one 'vape' on hand I feel. Some can and do pick up an ego and clearo and cheap juice and are happy for years with it, some of us need more variation and that means having to accept a higher initial layout for a healthier life.
We are at the mercy of vaper's toungue, withdrawal from the other substances in smoke other than nicotine and the fact that we need to mix it up to keep it interesting.
So yeah 3 on the go to be able to be picked up and vaped at any given time is a great option in my opinion.
