I recently transitioned from NLHE to PLO with good success, partially just due to the average PLO player being worse. I feel pretty comfortable with most of my game, but I'm getting stuck on how to play AAxx at around 60-120bb deep, and this problem is more of a problem in 6 max than HU.

The problem is that with AAxx, I 3-bet pot preflop and get called, so there is ~20bb going into the flop. On the flop, I usually c-bet to ~15bb (with my sizing mostly dependent on effective stack sizes), and then I get shoved on for ~45bb more by the smaller stacks and I get re-raised small then shoved on the turn by the slightly higher stacks. Villain's range is all sets, 2 pairs, monster draws, pair + good draws, and some KKxx, and I estimate that this range is re-raising me ~25% of flops. I find myself calling the re-raise ~70% of the time based on villain's stats, and I don't don't think the 75% won on Fold to C-bet is making up for the money lost when I get re-raised.

I can take some time doing out all the maths myself on whether my line is profitable, but can any experienced PLO players give a quicker answer on this? 

I also want to add that my PFR is around 20%, so it's not a case where I am only raising AAxx pre, but for argument's sake, let's say I am never getting shoved on with air.
