going through the same thing. Got some vanilla, RY2 (VG), and double mint from liberty-flights, couldn't taste any of them, so i bought some strawberry fields and a custom flavor from gourmetvapor, and still can't taste them. I too am using a Riva with both 510 LR and 306 LR attys. Every now and then I get a great vape and can taste the flavor, but most of the time I get no flavor at all, just the smell of the juice in my atty.
I asked a similar question and one response I got was that if you're just quitting smoking, your taste buds are damaged and flavors will come out nicely in due time. I don't know if you just quit but I did, its been about a week and a half since I've had more than 3 analogs in a day, and none for the past 5 days. I too am finding it really frustrating.
I don't think it's the juice, because gourmetvapor has gotten awesome reviews, and I can smell the juice from 5 ft away. I got double and triple flavor on my juices too.
I think we may need to switch up flavors; I notice flavors come out more if I have had food or a drink, and even more so if I vape a completely different flavor, like going from mint to strawberry. I'm planning on buying an Ali'i which has a 6 ml juice feed system, which is going to make switching flavors a bit difficult, so hopefully the taste buds come back and I wont need to keep switching.
good luck.
