I'm assuming that when you say "on the bubble" you mean that there only needs to be one last person to get eliminated before you get into the money if that is the case then you made the right move cause one of those players in front of you is going to lose and then you limp into the money.
Now if there were still several people left until the money then I would of probably would of shoved all in and closed my eyes and hoped for the best.
I play alot of sng's over on carbon and I run into situations like this all the time, not necessarily with a pair of aces though.
