I'v tried the unflavoured, not the biggest fan of it. I could get used to it, if I had to.
I make over 30 different recipes I have found or made my self over the years.
Flavouring for me is kind of important, I find the more I like the flavour, the more I will hit that atty/BF'er

TBH I spend more on flavouring than any other DIY supply
Over the years I learned all flavouring is not created equal

If I find the flavouring is quickly gunking up my coils, I will not use it any more!
As my DIY'ing has progressed over the years, I find my self using Flavour Art more & more, their flavouring is clean & relatively small percentages make a nice "Clean" Juice
I still use the Hawk Sauce from MBV @ 10%, I like it! & it keeps my coil relatively clean for a long time. I see MBV has it back as a "Flavour Shot", not in stock last few times I checked

I hope it come back in stock, it's one of those flavours I will never get boarded with
