Flush card comes on river, improves my hand.

I don't think your getting a fold from any better hands (AK/AQ, two pair) on the river. Also I can't see that many calls by villains with 55, 44, K7 etc. The best you can hope for is that you get a call by a range of [A8-AT,A5,A4]. Since your hand can take no heat, I think it is best to use it for its showdown value.
