D'addario chromes seem to be really well rated (Though i love my TI's)

Ernie Ball cobalt flats are nice & bright, and there is a range of sets. I really like the lightest set on my thunderbirds but so you can choose a heavier set for more tension.

@Sharkfinger I wish I could find them in Poland or at least some in Thomann or some shops in Czech Republic but GHS Boomers is what I only found. I like the sound of Bernard Edwards (Music Man used to offer bass players 1 set of roundwound, set of heavy flats and 2 sets of half-rounds made for them by GHS and he used probably the HR because this sound is too mellow for rounds but with kind of snap which cannot find in flats, but anyway...) Thanks for advice.
