Have a look at Mom and Pops pre-mixed concentrates. They are all I use, after a few early mistakes. I'm a tobacco/dessert vaper, and their stuff is lovely.
Go onto their US site to get a full description of their juices. A few UK sites stock them.
Using a pre-mixed concentrate isn't that much more cost than a pure diy.
Was gonna say exactly this. I had a frustrating time several months ago with mixing online 'clone' recipes, and indeed still do to a degree. What got me through my months in the 'mixological wastelands' were one-shot concentrates from Mom & Pops, Master Baker (Mount Baker), Chefs Vapour's own Concentrate blends and Decadent Vapour. Best one-stop-shop for these in my opinion is Chefs Vapour.
I have now found a good selection of ready-blended concentrates that cost WAY less than buying pre-mixed stuff but taste just as good, that keep me toke-happy while I play with 'proper' mixing ( some reviewed on my blog )
As has been mentioned, taste IS subjective, and I do find a lot of the 'clone' recipes very poor indeed. There are other amateur(ish) mixologist on another popular e liquid mixing forum that do put together some very good recipes of their own devising, but the only real solution is to find concentrates YOU like the taste of and start mixing up your own stuff, either from scratch or loosely based on other recipes published.
So far, I personally found, Flavourart concentrates to be a solid range to start mixing with, as their % usage is fairly consistent across the range ( 1-4%) unlike others than can vary wildly from 1% to 15% for the same manufacturer ( TFA/PA for example )
More recently I've been enjoying Flavorah for the very same reasons. Yes, there are some TFA/PA, CAP, INW etc thet are good, some that are not, but unfortunately each person has to find his own personal preferences... and this can be costly getting there!
Oh, and if a recipe isn't to your liking once mixed, just do what a lot of manufacturers probably do... add a hefty dose of sucralose!
