That is a lot of creamy goodness!
I know you like to use a lot of flavouring in your recipes, so I am not sure how sensitive your palate is to the Butyric acid notes, but I do seem to be in the minority when it comes to tasting these things (along with alcohol) in the juices. Next order I make for flavourings I will make sure to get some Bav Cream (probably DX) and use a scaled down version of your strawberry & cream recipe.
I am still in the camp that thinks that Diketones may not be as bad as people think, along with thinking that the replacements are likely to turn out to be just as bad. Much like sugar being replaced by sweeteners in sodas etc.
I've tasted a couple flavors that were anywhere from "eww" to "gag me with a fork" -- Capella's Vanilla Custard v2 in the first category, which is what sent me to Vanilla Swirl. TFA's Malted Milk is definitely in the 2nd category, or as i described it recently in the TFA thread, "gag a maggot."
The reason my strawberry & cream is so high in flavor is because I'm a STRONG adherent of
@Bill's Magic Vapor's "HFM" (high flavor mix) to avoid that tedious steeping, but if steeping doesn't distress you, it could probably be made half as strong, (though you'd probably want to keep the sweetener around 2%) and be just as good -- I just prefer to have something vapable within hours, not weeks.
The butyric acid is why I wouldn't use the DX Bavarian as a stand-alone; you're right, it's not a very pleasant flavor when mixed very strong, as for a stand-alone, but with the Vanilla Swirl (which doesn't have that ickiness at all), and in the background, it's not really noticeable -- the shisha strawberry is strong enough to completely cover anything like that -- the most authentic strawberry flavor I've tried.
TFA's Whipped Cream is diketone-free; it does contain triacetin, and it's a very light flavor, but if you mixed a combo of DX Bavarian, Vanilla Swirl, Whipped Cream, and Capella's Sweet Cream (diketone-free, and not icky at all -- a VERY authentic flavor), you'd end up with a very nice, very creamy flavor, without diketones.
I agree that most of the hysteria RE: diketones is exactly that, hysteria; nothing hard and fast is really known at this point. But since the only symptom of
bronchiolitis obliterans is shortness of breath, and I have asthma so I'm frequently short of breath, and the fact that B. O. is irreversible if it does occur, is why I avoid diketones as far I'm able to. It just seems to be one of the cases of "better safe than sorry," but it must be admitted -- the shisha strawberry is an organically-derived flavor, so it's entirely possible that it's not diketone-free -- Inawera hasn't made any statements either way about any of their flavors, to my knowledge. This is one reason I *have* started reducing flavor percentages in that recipe; so far I've reduced all flavors in it except the sweetener, by 5% -- still very highly-flavored, but I figure as my tastebuds continue to recover, I'll probably be able to continue reducing the flavor, very slowly.
