Play 1 table until you can grasp the variance. It is nuts. Position is so so important in PLO, even moreso then NLHE. Wait for those epic hands and just be very careful about what hands get there on the flop turn and river.
Always bet pot so no one can put you on a range.
So should I be playing a lot of tables
What I mean above is to play 9 handed one table and not to play many tables.
The table dynamics might be different which favor your style.
