This is only rouge estimate. Mint and menthol - Most of those I've used are good shake and vape but mellow and get smoother over time. Fruit and candy - are often S&V but will change over time either mellowing or a few will get stronger. Creams, coffee, tea and bakery - a few might be S&V but most are better with a week to a month steep. Custards - are usually best with over a month steep. I've heard differing views about tobacco, chocolate and nutty flavors but I don't use them very much so I really shouldn't advise.
Keep in mind this is a very simplified generalization. Many flavors act differently for different people.
