Level 6 ATo push OOP with 1 limper

[Isura]

The limper is pretty loose (limps a lot) preflop. The chip leader had previously pushed me all-in on my steal attempt with K5 with I folded. But overall he is not bullying the table by any means. I'm not sure about this push. Does raising to say 600-700 accomplish the same purpose or do you guys play it the same? My thinking was that with a raise of 700 I would be put all-in by the big stack, and the loose UTG might call with hands like AQ-AT. I obviously have to call if SB pushes right?

BB (t2245)
UTG (t2455)
Hero (t1405)
CO (t1110)
Button (t1645)
SB (t4640)

Preflop: Hero is MP with T/images/graemlins/diamond.gif, A/images/graemlins/spade.gif.
UTG calls t200, <font color="#CC3333">Hero raises to t1405</font>

Edit: This is a Stars 5 + .50 FWIW.

I don't like this so much, unless the table is folding to lots of raises. Your position is early, needless to say and some pocket pairs may call you depending on the buyin
