Crazy Pineapple 8b discards

[Yads]

I tried playing a bit of micro limit Pineapple hi/low on UB and I'm really confused on how to discard in this game. Let's say you raise PF with AQ2 rainbow (is this even a good play?) flop comes Q46 two of one suit. Let's say you bet and get called in 3 places. Do you dump the 2 and go for high? Dump the Q and go for low? what if your Q2 is suited and you flop a 4 flush with the same board?
