I'd never raise the river because you are only (usually) called by a hand that beats you - and it usually re-raises, too. You may lose a few chips the odd time he has Jx but it is compensated for the times you save chips when he has you smashed.

Also, I don't think he is on the straight draw on the flop - I put it at less than 10% chance. This was my thought process at the time anyway.
