Playing AA in the 1st level

I got to play just one hand in the big Poker Stars Sunday tournament. I have been thinking about this hand and maybe I just need to make a monster reraise with a big pair in this level preflop, since they seem to play just about anything to flop big (my opponent had Ah9s in this hand). I don't really know, let me know your thoughts on the best way to play AA with deep stacks in the first level of the tourney.

November results

I played just 8 tournaments in November and played a grand total of 0 hours in cash games. All the tournaments I played were Stars tournaments, this is the list:

11/21/06 PS NLH $200+15 3088 out of 6733
11/26/06 PS NLH $200+15 194 out of 1050
11/28/06 PS NLH Rebuys $100+9 (Spent $309) 165 out of 197
11/28/06 PS NLH $100+9 49 out of 377
11/28/06 PS NLH $150+12 372 out of 956
11/30/06 PS NLH $300+20 558 out of 758
11/30/06 PS NLH $100+9 60 out of 270
11/30/06 PS NLH Rebuys $100+9 (Spent $309) 5 out of 167, FT, won $3,984.50

ITM: 1/8 FT: 1/8 Total Spent: $1748 (Rake: $98) Total won: $3,984.50 Profit: $2,236.50

I luckboxed my way to the FT in the last tournament I played in the month, besides that the rest of them were the usual amount of frustration. One good thing is I finished in the black and I'm ready to work in December, my goal is to play at least 100 tourneys. Let's see if I do it.
