have you tried learning Czech?
Yes, I love the sound of Czech and Czech movies and tv series and Czech classical music (Czech pop tends toward the mid... it has its moments but overall it's nowhere near as good as Polish or Romanian). And I like that they dub more than use lektor (I can watch a series or movie with the lektor if it's not in English... but lektor over English is fingernails on a chalkboard).
What I don't like so much about Czech is the big split between the formal literary and everyday spoken languages (and some aspects of archaic Czech spelling, like jsem) the closer relation to everyday and formal Polish (and general lack of really strong regional variation) is a big plus for me.
All together, had there been an opportunity to go to Czechoslovakia instead of Poland back in my university days I might well be in Czechia now... but that didn't happen. And probably for the best, not least because Czech 'cuisine' is pretty limited... compared to Polish fun for a week or so as a tourist but long term... yikes! And Czech political culture is more unstable than Poland... the highs are pretty good but the lows are really, really low.
But I had to give up trying to really learn Czech well. Again, for a non-slav trying to keep Polish and Czech separate in the head.... not fun, much harder than keeping different Romance languages apart.
