Never had any revolting tastes. Some flavours I've liked more or less than I do in food/sweets - funny that though I love cherry, raspberry and apple flavours in sweets, they don't really work for me in e-juice.
I've just started using some PG based food flavourings which are lovely. I did get a cream flavour (a bit of a gamble, as I'm not really a cream fan) - it is VERY creamy. Personally, on first vape, I found it a little sickly ( though that could well just be me), so I've used it very sparingly in a coffee/cinnamon blend, and it works well.
I'm currently vaping the Irish Cream as it comes in a 50/50 16mg, and it's very nice (not quite as good as the Irish Coffee, but still good).
As for blending, I make up my base without flavour (adjusting quantities to result in 50/50 16mg once flavour is added). When I blend, I pop flavours in the bottle and judge largely on smell test on the first attempt, then add the pre-mixed base. I then leave them in a drawer with the lid off and give em a daily squeeze for at least a week.
My main blends are Coffee/Toffee or butterscotch/cinnamon/cream and banana/butterscotch (the latter I tend to mix at 50/50 per flavour). the latter is my favourite ADV.
