[Village Idiot]

8 handed.
Blinds are 400/800. Levels are 30 mins and we have about 15 mins left at this level. No antes.
I have 5,500, 2nd shortest stack. All stacks to act nehind me are larger.
Avg. stack size is 10,000.
Top two get paid.
A4s from UTG + 1.
First hand at the final table but, everyone at the table except 1 guy has played with me before and should know how tight I usually am pre flop.

My image is tight. In the last 30 mins at one of the two remaining tables I showed AQs that I had to throw away after a flop all in bet in front of me by a larger stack when the flop totally missed my hand and i read the all in as having me beat.

Is it better here to just raise to 2,400 to give the perception of having a big hand you want action on, then put ther rest in on the flop depending on reads and the flop ? Or just shove all in pre flop ?
Betting 2,400 leaves me 3,100 back which is large enough to chase out a drawing hand only on the flop if I only get 1 caller.

Or is this a clear fold and wait for a better hand ?
