Too Aggro With A3s Here?

[Unarmed]

Villain isn't brutal, my whole stack has been built through steals. Was just about to change things up but for some reason I decided to push one more.

$5 PokerStars No-Limit Hold'em Tourney, Big Blind is t200 (5 handed)

BB (t4222)
UTG (t3079)
MP (t771)
Button (t2067)
Hero (t3361)

Preflop: Hero is SB with 3[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/spade.gif[/img].
UTG calls t200, MP folds, Button folds, <font color="CC3333">Hero raises to t3361</font>

Just generally, how does everyone feel about pushing to 1 or 2 limpers? I actually used to fold this as whenever someone limped I would automatically eliminate stealing as an option.

Also, assume you are going to try to steal this, is pushing really the best bet size? I can't remember the last time I put in a normal raise 4 or 5 handed (regardless of my stack) but perhaps this isn't optimal play.
