Straight Flush
Based on our betting pattern, I would expect villain to call with any low, even if they have just a one pair high hand, "just in case". I don't think we're folding out any high-only hands that have us beat (A33x for example) plus there's a very real chance villain has A4xx in their range and wants to check raise us into oblivion. I think the odds of villain having two worse pair with no low and calling us is worse than us getting a call from a better hand, or worse, getting check-raised.
