Big draw with awkward stack sizes

[edge]

5/10 6-handed. I have been stacked once or twice already at this table. UTG folds, two callers, I make it 50 on the button with A[img]/images/graemlins/diamond.gif[/img]K[img]/images/graemlins/diamond.gif[/img] and 1150 behind. Unknown SB calls with 725 behind, BB folds, TAG UTG+1 with 1600 behind calls, very aggressive CO calls with 1050 behind.

Four to the flop of Q[img]/images/graemlins/diamond.gif[/img]J[img]/images/graemlins/diamond.gif[/img]4[img]/images/graemlins/spade.gif[/img] and 200 in the pot.

SB checks, UTG+1 bets 160, CO folds. I have 1100 left, UTG covers. What's my move?
