raising AJo into a field of 6 limpers (+BB) is a bad idea. There is very little chance you are taking it down preflop and then you are left with a bad hand out of position, with a large pot.

Raising the flop and turn is fine, but after the turn I'd have serious questions about what the villian has. I'd probably end up check/calling the river, or check/folding the river depending on what I put the villian on. There are very few hands that you beat with TPTK that play this way.
