Hero sb AcAs6cQs (200 stack)

Couple off limpers, STEAMED-station-LAG pots on BTN to 7
Hero calls and so does rest off table about 5-6 way dont remember.

Flop Tc8c9s Hero x, random donk to 5, 3 callers fish raises to 40.
Hero calls, rest folds and last player also calls.(both fish and him covers hero)
Turn 3s Hero x, DONK pott fish folds hero?

I know I should probably 3-bet pre here every time but I am experementing with a new call strat so not really interested about preflop. It was also several shortys at the table who liked to limp-raise and since the fish WOULD never fold to a 3-bet Hero could 4-bet.

My question is whats best flop and turn line?

Call flop seems best with multiwaydraw and alot off turns makes my hand much easier to play.
On the turn the donk was strange, would he flat on the flop with QJ**, to me it seems he picked up some extra draw like QKsTxs?
