I'd honestly recommend seeing if you have any local brick and mortar tea vendors so you could go get your nose in some tins. If you already know you like breakfast blends, you will get such a better experience from your tea if you can really smell the leaves and let your nose lead the way. Tea doesn't always taste how it smells but a lot of the major notes will be there. If you are unfortunate enough not to have a local place, then if you're in the US, Adagio has lots of samplers and they're usually my go to.
