I think the big bet concepts are harder to learn than the other stuff, sounds like I'm in the minority though.

Put another way, as someone whose closest descriptor before getting into PLO was $30/$60 LHE 6max player, I had a LOT to learn about big bet. 6max limit holdem is all about not folding on later streets, PLO takes a lot more folding on later streets. The aggression of limit 6max is helpful though. But the thing that helped my PLO game most coming from that spot was reading David and Ed's NLHE book, oddly enough, so I think those big bet concepts are pretty key.
