When he donks the flop I don't think he is so strong, mostly, 9x, 7x, occasionally weak Flush (even then possibly would c/r , but my be going for bet/shove given stack size) less often may have FD but not so likely seen as I have A 
. Given his weak range I opt to raise flop , shove turn vs. mid stack expecting a ton of fold equity and deecent pot equity when he decides to call off a 9x hand.
Aggro line better than passive ?
You wont make such an opponent to fold those hands. Rather take the implied odds and reevaluate on further streets.
