50+5: Should I have pushed w/ATo vs a min raise?

[AA suited]

Party Poker No-Limit Hold'em Tourney, Big Blind is t100 (8 handed) converter

MP2 (t730)
HERO (t1150)
Button (t930)
SB (t1205)
BB (t1220)
UTG (t1145)
UTG+1 (t1645)
MP1 (t1975)

Preflop: HERO is CO with T[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/club.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">UTG+1 raises to t200</font>, <font color="#666666">2 folds</font>, <font color="#CC3333">HERO raises to t1150 (All-In)</font>,

No reads since I was multi-tabling.

My experience has been that min raisers are weak, and will fold to strength.

Should I have just called instead?

What would you have done?
