Well it sounds like we have similar taste. I don't like the fruity stuff either. I like tobacco based flavors.
RY4 is a stronger tobacco flavor with a touch of sweet. Some mixes are more sweet then others and unfortunately Dekang and all
juice makers don't seem to be 100% consistent. I vape the same flavors normally and batchs can taste different. Not huge difference but the flavoring seems more in some then others. Maybe try a small bottle of RY4 again in the future.
Always try small bottles at first, nothing worse then getting a huge bottle and then not liking it.
With that said heres a few to consider
555 - Strong flavor with a nutty taste. THis has some good throat kick
DK-Tab - this is my favorite flavor but some hate it. It tastes sorta like brown sugar to me or maple. I have a har dtime describing flavors.
Camel/blended/turksh blend - these are all similar to me and have slight changes in the rich side taste. It doesn't taste like straight tobacco but I ahve a hard time pinning down the side taste of these flavors. Overall I enjoy them
RY1 - this has more flavor then RY4. Sorta of a mix of 555 and RY4. Strong throat hit
Tobacco/kent - I like these for straight tobacco flavor
Cotton Candy - this is one of the only candy or fruit flavors I can do, it doesnt have that over the top sweet taste
