is x/r'ing the best play here? I felt that just calling might be a little too weak seeing as several turn cards are very bad for our hand, as well as the fact that this hand could get tricky to play OOP

Not sure about this bet/fold at all. Figured most of his ss hands and missed straights would be folding and checking leads to me folding most rivers. Perhaps this hand is too high in my range to be betting but I do think I can jam quite a few rivers if he called the turn bet. I also believe that this could be a call since his jamming range here has a high % of draws.
