First bait caster

My first bait caster arrives Tuesday I’m questioning my line choice I went with 20lb test braid but based that off of the recommended mono weight. My question being the true braided equivalent to 20lb mono is like 60lb braid roughly. My question is should I have gone heavier or is 20 going to be okay!!!…. I’m over thinking this. But I’m throwing 30lb braid on my spinning reel 40 series…
