Hi - I seem almost immune to "sweet."

I got a bottle of straight sucralose from TFA, which tastes insanely sweet on my finger, but I can barely taste it if added to a
vape.
Another sweetener often used is Ethyl maltol, which is the cotton candy-type sweet. I got some as sweet as I could order, plus as many flavor shot offered from ECBlend, and I can taste the sweet, but to me it has a "dry" aftertaste like real cotton candy. I currently have a mixture of the cotton candy, sucralose and marshmallow in a
tank and I'm almost getting the sweetness that I want, but I haven't added any flavors yet - I'm afraid it will make the sweet taste go away. This isn't DIY, I just mix up flavors I get from vendors (except the sucralose).
Stevia is another sweetener some people use, but I've never tried it.
If you find a killer sweet vape, please let me know.
