I played 13/5(2) OTB. I didn't consider 13/9(4) seriously, in part because my pattern recognition didn't kick in since the four-down play doesn't clear the midpoint. Note also that since there are only 3 checkers on the 8pt, not all doublets play as nicely as they do when there are 4 checkers on the 8pt. Still, four down creates a lot of extra flexibility and goes a long way to clearing the midpoint. The rollout puts it on top, though not by a huge margin.
