Best sampler? - eviltoast

Hey, folks! I’m fairly new to hot teas. I’ve been very much so enjoying my English and Irish breakfast teas, Earl Grey, and a few other Walmart specials. But I find that I think most of them taste weak, and i use multiple bags. I’d like to try a loose leaf, and maybe something a little stronger. I’m not a fan of green tea for the same reason, it feels weak/watery. I’m a US southerner, so I guess I sort of ruined myself to tea strong enough to get out the pot and slap you. Haha.

Can anyone recommend a sampler of stronger teas? I have a fancy kettle that you can set the temperature on if they need some specific temp, as I know some teas do.

Any help is appreciated! Thanks in advance!
