Lately whenever I attempt a squeeze with a similar hand it seems I frequently get called by a bigger ace. Should I just completely avoid making squeeze plays with A8s-ATs?

I know having 9Ts is probably better when you do get called, but do you think I get called by worse hands, pocket pairs lower than 99 or get everyone to fold enough of the time here to make this a +EV play? I needed to accumulate and this looked like a pretty good spot. All thoughts appreciated.
