If there were any players to act after you I'd consider a fold as a strong option given the fairly large field. Since you close the betting on this round I think a call is okay. A raise is no good, given the possibility of a reraise, which would make you puke. I think the valuation of your hand of being worth 7 outs may still be a bit optimistic, given the size of the field. A fold would not be all that bad here becauese if you improve you still must call a bet on the river in most situations with a weak made hand. If you want to put yourself in that spot, call; if not, fold.
