I have found that some people that are extremely sensitive to taste are sometimes unable to get the taste they desire form a genesis style atomizer. That said taste from a gene style can be affected by a number of things and can be different from atomizer to atomizer. The thing that I have noticed that's the biggest factor for taste on my atomizers (AC9, BliSS, G-
tank-US, Z-Atty Pro, DuD) is the actual chamber size and size/position of air hole in relation to chamber size/shape.
Example:
My ZAP has IMO a small chamber considering it's size with the air hole "higher" in the chamber. This creates the need for a lighter draw and the vapor is far more concentrated giving far more flavor than say the AC9.
The AC9 has a larger air hole, bigger chamber and the airhole is lower in the chamber.....this make for awesome huge amounts of vapor but the flavor is not quite as "sharp"
The BliSS, is kinda right in the middle with tons of vapor and less flavor "muting" but still not quite as sharp as the ZAP
The G-
tank is waay different, really small vapor chamber with lot more distance to the drip tip allowing the vapor to concentrate and give the best flavor(for me at least)
I don't have a Cobra but from what I have seen and heard I would prolly put it somewhere between the AC9 and BliSS in terms of flavor...as a guess. Point is not all genesis style atomizers are equal, I use each of mine for different scenarios. The Cobra might not be as good for you as say a ZAP.
One thing to try is to go with a 5/6 of say 30g and back off the voltage a bit, I've had success getting more flavor that way.
Not to disappoint but it might also be that the taste of a genesis style (or SS in a gene) might just not be for you, There are some out there that I know with super sensitive taste buds and just can't seem to get the flavor they want with a gene style.
Personally I find that even with a little muting of flavor I still feel that the taste is still more "pure" than from any standard atty or carto......but again that's just me.
