My first 5/10 decision

[octop]

Im playing my first ever 5/10 table
I was watching this table for about 20 mins and there are 2 donkeys in this game, but they are not involved in this hand.
UTG doubles the blind, 3 or 4 callers and I call with AJh on the cutoff.
Flop
Ace King 6 2 spades, 1 heart
UTG bets 30, UTG+1 makes it 60 folded to me and I make it 180, UTG folds and UTG+1 miniraises back.

I h ave not played with the villian in about a year when I played 1/2 with him. He was god awful back then, but in the time Ive been watching has not gotten out of line at all. What is my move?
