AA flop decison, too nitty?

[0uTpLaYeD]

I have been playing at 18/15/3.4 and Cbetting 80% of
flops so far.


Poker Stars - No Limit Hold'em Cash Game - $0.10/$0.25 Blinds - 5 Players - (LegoPoker Hand History Converter)

SB: $10.70
BB: $19.30
UTG: $17.40
Hero (CO): $29.10
BTN: $27.25

Reads: <font color="blue">Villain is 17/14/1.5 over 89 hands.</font>

Preflop: Hero is dealt A[img]/images/graemlins/diamond.gif[/img] A[img]/images/graemlins/spade.gif[/img] (5 Players)
UTG calls $0.25, <font color="red">Hero raises to $1.25</font>, BTN calls $1.25, 2 folds, UTG calls $1.00

Flop: ($4.10) 5[img]/images/graemlins/club.gif[/img] 3[img]/images/graemlins/heart.gif[/img] 2[img]/images/graemlins/club.gif[/img] (3 Players)
UTG checks, <font color="red">Hero bets $2.50</font>, <font color="red">BTN raises to $8.00</font>, 2 folds

How would our line change if the villains stats were 21/19/4?
