EPT London hand

[mic_check12]

Background

About halfway through the 1st level. Hero has been active, was down to 2k early after getting a set cracked by a straight draw. Have shown down K7s after raising in ep and betting 2 streets with a flush draw. Now back up to 9k after winning a couple of pots(one with AA doubling through villain's QQ). Villain has been fairly quiet, open raising once or twice preflop (but only showing down the QQ with which he reraised an ep raise from mp). Sorry for all the info but I want this to be detailed.

The Hand

UTG limps (has limped a lot of pots), Villain limps utg+1, hero raises to 350 (bb 50), villain is only caller.

Flop is 9h 5c 5h (pot 825)

Villain leads for 300, hero raises to 900, villain shoves for a massive overbet. Calling would leave hero with 1600 while folding would leave 7500. Aside from the obvious 99 and 55 what hands can/should hero call with?
