I prefer 1:1 on my blitzing LB. It seems to work better than the 3:2s and 4:3s I see (I led LBs in sacks this season in my league). Honestly agility is better for coverage too since most LBs don't play deep man coverage and don't need to keep up with speedsters WRs. But then there's so many speed whores I'm sure they'll shout me down soon or something.
It's all gonna depend on who you ask and there won't be a once and for all answer, sorry
