TV butter rum is strong - but you gotta like rum
I also LOVE his strong flavors - no point in subtle for me at times lol - and my other faves are: Pina colada (gotta like pineapple, and this is now my #1 fave of TV), German choc cake, (have it with extra choc for a full bodied vape) Mint choc chip (this one varies from person to person as far as choc/mint strength tastes, from reading posts, but there IS a lot of mint so if you don't like mint dont get it), TV
tobacco - its strong but it takes a while to get there - if you dont mind waiting, then its very good (and mixes with pretty much anything).
The cafe mocha (and macciato) is very strong too - but again it can be an aquired taste.
AC will blow your head off - its possibly the strongest vape Ive ever had - so I have to let it mellow big time, n can't vape it all day (my hat is off to those that can lol). If you love cinamon and strong flavor (and TH) then get it.
Another Ive found strong: Irish cream.
Hopefully that helped some; do remember that taste is subjective, and battered tastebuds take some time to recover after smoking, so something which may not be flavorful NOW might knock your socks off in 2 months lol.
