You are looking for a pool website that just solved a solo block to encourage your mining journey? I don't know how this will help because just because a solo mine was solved on a pool doesn't mean you will be lucky on the same pool, do not worry yourself, just find a popular bitcoin mining pool and connect your asic miner, since you have a long term goal you will be fine.
I suggest you leave things at default settings and let the asic do its thing, you claimed you as ready to do this for long, how long are we talking about?
Visit CKpool itself and pretend as if you want to connect your miner, you will be given different server location, USA and others should be present there.
Every miners always want to be sure that they are on the fastest server I get it, you can use this to do your thing.
