Definitely try the BASIC tobacco sampler pack. My favourite of those is Tabacco #2 which is strong and sweet and I like to use it when I need a change up from menthols and fruit flavours.
I regularly use ECOpure Menthol which is light and can vape it all day. Same with the 'rich' ECOpure flavour.
I prefer menthols mostly and fruity flavours. I would also try
Forbidden from cignot which is very nice.
Recently tried their Double Mint and looking forward to ordering a big bottle of that when I need juices again.
If you like coffee flavours, the Cafe Brasiliano from Totally Wicked smells and tastes just like a milky coffee with sugar, I like it for once in a while but could never do it all day.
