This is fine, you're also allowed to check flop or bet turn. Hard to say which of the lines is going to best against a villain without reads on him, x/c x/r, b x/r, b b b are all meant to be around the same value though. You could try making some assumptions about how he plays and throwing the hand in CREV to see which you think is best but it'll be quite a large problem because of how many different turns and rivers there are.
